+High Performance, Feature-Rich Idiomatic Go codec/encoding library for 
+binc, msgpack, cbor, json.
+
+Supported Serialization formats are:
+
+  - msgpack: https://github.com/msgpack/msgpack
+  - binc:    http://github.com/ugorji/binc
+  - cbor:    http://cbor.io http://tools.ietf.org/html/rfc7049
+  - json:    http://json.org http://tools.ietf.org/html/rfc7159
+  - simple: 
+
+To install:
+
+    go get github.com/ugorji/go/codec
+
+This package understands the 'unsafe' tag, to allow using unsafe semantics:
+
+  - When decoding into a struct, you need to read the field name as a string 
+    so you can find the struct field it is mapped to.
+    Using `unsafe` will bypass the allocation and copying overhead of []byte->string conversion.
+
+To install using unsafe, pass the 'unsafe' tag:
+
+    go get -tags=unsafe github.com/ugorji/go/codec
+
+For detailed usage information, read the primer at http://ugorji.net/blog/go-codec-primer .
+
+The idiomatic Go support is as seen in other encoding packages in
+the standard library (ie json, xml, gob, etc).
+
+Rich Feature Set includes:
+
+  - Simple but extremely powerful and feature-rich API
+  - Very High Performance.
+    Our extensive benchmarks show us outperforming Gob, Json, Bson, etc by 2-4X.
+  - Multiple conversions:
+    Package coerces types where appropriate 
+    e.g. decode an int in the stream into a float, etc.
+  - Corner Cases: 
+    Overflows, nil maps/slices, nil values in streams are handled correctly
+  - Standard field renaming via tags
+  - Support for omitting empty fields during an encoding
+  - Encoding from any value and decoding into pointer to any value
+    (struct, slice, map, primitives, pointers, interface{}, etc)
+  - Extensions to support efficient encoding/decoding of any named types
+  - Support encoding.(Binary|Text)(M|Unm)arshaler interfaces
+  - Decoding without a schema (into a interface{}).
+    Includes Options to configure what specific map or slice type to use
+    when decoding an encoded list or map into a nil interface{}
+  - Encode a struct as an array, and decode struct from an array in the data stream
+  - Comprehensive support for anonymous fields
+  - Fast (no-reflection) encoding/decoding of common maps and slices
+  - Code-generation for faster performance.
+  - Support binary (e.g. messagepack, cbor) and text (e.g. json) formats
+  - Support indefinite-length formats to enable true streaming 
+    (for formats which support it e.g. json, cbor)
+  - Support canonical encoding, where a value is ALWAYS encoded as same sequence of bytes.
+    This mostly applies to maps, where iteration order is non-deterministic.
+  - NIL in data stream decoded as zero value
+  - Never silently skip data when decoding.
+    User decides whether to return an error or silently skip data when keys or indexes
+    in the data stream do not map to fields in the struct.
+  - Detect and error when encoding a cyclic reference (instead of stack overflow shutdown)
+  - Encode/Decode from/to chan types (for iterative streaming support)
+  - Drop-in replacement for encoding/json. `json:` key in struct tag supported.
+  - Provides a RPC Server and Client Codec for net/rpc communication protocol.
+  - Handle unique idiosyncrasies of codecs e.g. 
+    - For messagepack, configure how ambiguities in handling raw bytes are resolved 
+    - For messagepack, provide rpc server/client codec to support 
+      msgpack-rpc protocol defined at:
+      https://github.com/msgpack-rpc/msgpack-rpc/blob/master/spec.md
+  
+Extension Support
+
+Users can register a function to handle the encoding or decoding of
+their custom types.
+
+There are no restrictions on what the custom type can be. Some examples:
+
+    type BisSet   []int
+    type BitSet64 uint64
+    type UUID     string
+    type MyStructWithUnexportedFields struct { a int; b bool; c []int; }
+    type GifImage struct { ... }
+
+As an illustration, MyStructWithUnexportedFields would normally be
+encoded as an empty map because it has no exported fields, while UUID
+would be encoded as a string. However, with extension support, you can
+encode any of these however you like.
+
+RPC
+
+RPC Client and Server Codecs are implemented, so the codecs can be used
+with the standard net/rpc package.
+
+Usage
+
+The Handle is SAFE for concurrent READ, but NOT SAFE for concurrent modification.
+
+The Encoder and Decoder are NOT safe for concurrent use.
+
+Consequently, the usage model is basically:
+
+    - Create and initialize the Handle before any use.
+      Once created, DO NOT modify it.
+    - Multiple Encoders or Decoders can now use the Handle concurrently.
+      They only read information off the Handle (never write).
+    - However, each Encoder or Decoder MUST not be used concurrently
+    - To re-use an Encoder/Decoder, call Reset(...) on it first.
+      This allows you use state maintained on the Encoder/Decoder.
+
+Sample usage model:
+
+    // create and configure Handle
+    var (
+      bh codec.BincHandle
+      mh codec.MsgpackHandle
+      ch codec.CborHandle
+    )
+
+    mh.MapType = reflect.TypeOf(map[string]interface{}(nil))
+
+    // configure extensions
+    // e.g. for msgpack, define functions and enable Time support for tag 1
+    // mh.SetExt(reflect.TypeOf(time.Time{}), 1, myExt)
+
+    // create and use decoder/encoder
+    var (
+      r io.Reader
+      w io.Writer
+      b []byte
+      h = &bh // or mh to use msgpack
+    )
+
+    dec = codec.NewDecoder(r, h)
+    dec = codec.NewDecoderBytes(b, h)
+    err = dec.Decode(&v)
+
+    enc = codec.NewEncoder(w, h)
+    enc = codec.NewEncoderBytes(&b, h)
+    err = enc.Encode(v)
+
+    //RPC Server
+    go func() {
+        for {
+            conn, err := listener.Accept()
+            rpcCodec := codec.GoRpc.ServerCodec(conn, h)
+            //OR rpcCodec := codec.MsgpackSpecRpc.ServerCodec(conn, h)
+            rpc.ServeCodec(rpcCodec)
+        }
+    }()
+
+    //RPC Communication (client side)
+    conn, err = net.Dial("tcp", "localhost:5555")
+    rpcCodec := codec.GoRpc.ClientCodec(conn, h)
+    //OR rpcCodec := codec.MsgpackSpecRpc.ClientCodec(conn, h)
+    client := rpc.NewClientWithCodec(rpcCodec)
+

+package codec
+
+// Benefits of go-codec:
+//
+//    - encoding/json always reads whole file into memory first.
+//      This makes it unsuitable for parsing very large files.
+//    - encoding/xml cannot parse into a map[string]interface{}
+//      I found this out on reading https://github.com/clbanning/mxj
+
+// TODO:
+//
+//   - optimization for codecgen:
+//     if len of entity is <= 3 words, then support a value receiver for encode.
+//   - (En|De)coder should store an error when it occurs.
+//     Until reset, subsequent calls return that error that was stored.
+//     This means that free panics must go away.
+//     All errors must be raised through errorf method.
+//   - Decoding using a chan is good, but incurs concurrency costs.
+//     This is because there's no fast way to use a channel without it
+//     having to switch goroutines constantly.
+//     Callback pattern is still the best. Maybe consider supporting something like:
+//        type X struct {
+//             Name string
+//             Ys []Y
+//             Ys chan <- Y
+//             Ys func(Y) -> call this function for each entry
+//        }
+//    - Consider adding a isZeroer interface { isZero() bool }
+//      It is used within isEmpty, for omitEmpty support.
+//    - Consider making Handle used AS-IS within the encoding/decoding session.
+//      This means that we don't cache Handle information within the (En|De)coder,
+//      except we really need it at Reset(...)
+//    - Consider adding math/big support
+//    - Consider reducing the size of the generated functions:
+//      Maybe use one loop, and put the conditionals in the loop.
+//      for ... { if cLen > 0 { if j == cLen { break } } else if dd.CheckBreak() { break } }

+// CborHandle is a Handle for the CBOR encoding format,
+// defined at http://tools.ietf.org/html/rfc7049 and documented further at http://cbor.io .
+//
+// CBOR is comprehensively supported, including support for:
+//   - indefinite-length arrays/maps/bytes/strings
+//   - (extension) tags in range 0..0xffff (0 .. 65535)
+//   - half, single and double-precision floats
+//   - all numbers (1, 2, 4 and 8-byte signed and unsigned integers)
+//   - nil, true, false, ...
+//   - arrays and maps, bytes and text strings
+//
+// None of the optional extensions (with tags) defined in the spec are supported out-of-the-box.
+// Users can implement them as needed (using SetExt), including spec-documented ones:
+//   - timestamp, BigNum, BigFloat, Decimals, Encoded Text (e.g. URL, regexp, base64, MIME Message), etc.
+//
+// To encode with indefinite lengths (streaming), users will use
+// (Must)Encode methods of *Encoder, along with writing CborStreamXXX constants.
+//
+// For example, to encode "one-byte" as an indefinite length string:
+//     var buf bytes.Buffer
+//     e := NewEncoder(&buf, new(CborHandle))
+//     buf.WriteByte(CborStreamString)
+//     e.MustEncode("one-")

+//     encodedBytes := buf.Bytes()
+//     var vv interface{}
+//     NewDecoderBytes(buf.Bytes(), new(CborHandle)).MustDecode(&vv)
+//     // Now, vv contains the same string "one-byte"

+// followed by an optional comma and options.
+// Note that the "json" key is used in the absence of the "codec" key.
+//
+// To set an option on all fields (e.g. omitempty on all fields), you
+// can create a field called _struct, and set flags on it.
+//
+// Struct values "usually" encode as maps. Each exported struct field is encoded unless:
+//    - the field's tag is "-", OR
+//    - the field is empty (empty or the zero value) and its tag specifies the "omitempty" option.
+//
+// When encoding as a map, the first string in the tag (before the comma)
+// is the map key string to use when encoding.
+//
+// However, struct values may encode as arrays. This happens when:
+//    - StructToArray Encode option is set, OR
+//    - the tag on the _struct field sets the "toarray" option
+//
+// Values with types that implement MapBySlice are encoded as stream maps.
+//
+// The empty values (for omitempty option) are false, 0, any nil pointer
+// or interface value, and any array, slice, map, or string of length zero.
+//
+// Anonymous fields are encoded inline except:
+//    - the struct tag specifies a replacement name (first value)
+//    - the field is of an interface type
+//
+// Examples:
+//
+//      // NOTE: 'json:' can be used as struct tag key, in place 'codec:' below.
+//      type MyStruct struct {
+//          _struct bool    `codec:",omitempty"`   //set omitempty for every field
+//          Field1 string   `codec:"-"`            //skip this field
+//          Field2 int      `codec:"myName"`       //Use key "myName" in encode stream
+//          Field3 int32    `codec:",omitempty"`   //use key "Field3". Omit if empty.
+//          Field4 bool     `codec:"f4,omitempty"` //use key "f4". Omit if empty.
+//          io.Reader                              //use key "Reader".
+//          MyStruct        `codec:"my1"           //use key "my1".
+//          MyStruct                               //inline it
+//          ...
+//      }
+//
+//      type MyStruct struct {
+//          _struct bool    `codec:",omitempty,toarray"`   //set omitempty for every field
+//                                                         //and encode struct as an array

+//   - If it implements encoding.(Binary|Text|JSON)Marshaler, call its Marshal(Binary|Text|JSON) method
+//   - Else encode it based on its reflect.Kind

+// Fast path functions try to create a fast path encode or decode implementation
+// for common maps and slices.
+//
+// We define the functions and register then in this single file
+// so as not to pollute the encode.go and decode.go, and create a dependency in there.
+// This file can be omitted without causing a build failure.
+//
+// The advantage of fast paths is:
+//    - Many calls bypass reflection altogether
+//
+// Currently support
+//    - slice of all builtin types,
+//    - map of all builtin types to string or interface value
+//    - symmetrical maps of all builtin types (e.g. str-str, uint8-uint8)
+// This should provide adequate "typical" implementations.
+//
+// Note that fast track decode functions must handle values for which an address cannot be obtained.
+// For example:
+//   m2 := map[string]int{}
+//   p2 := []interface{}{m2}
+//   // decoding into p2 will bomb if fast track functions do not treat like unaddressable.
+//

+// ---------------------------------------------------
+// codecgen supports the full cycle of reflection-based codec:
+//    - RawExt
+//    - Raw
+//    - Builtins
+//    - Extensions
+//    - (Binary|Text|JSON)(Unm|M)arshal
+//    - generic by-kind
+//
+// This means that, for dynamic things, we MUST use reflection to at least get the reflect.Type.
+// In those areas, we try to only do reflection or interface-conversion when NECESSARY:
+//    - Extensions, only if Extensions are configured.
+//
+// However, codecgen doesn't support the following:
+//   - Canonical option. (codecgen IGNORES it currently)
+//     This is just because it has not been implemented.
+//
+// During encode/decode, Selfer takes precedence.
+// A type implementing Selfer will know how to encode/decode itself statically.
+//
+// The following field types are supported:
+//     array: [n]T
+//     slice: []T
+//     map: map[K]V
+//     primitive: [u]int[n], float(32|64), bool, string
+//     struct
+//
+// ---------------------------------------------------
+// Note that a Selfer cannot call (e|d).(En|De)code on itself,
+// as this will cause a circular reference, as (En|De)code will call Selfer methods.
+// Any type that implements Selfer must implement completely and not fallback to (En|De)code.
+//
+// In addition, code in this file manages the generation of fast-path implementations of
+// encode/decode of slices/maps of primitive keys/values.
+//
+// Users MUST re-generate their implementations whenever the code shape changes.
+// The generated code will panic if it was generated with a version older than the supporting library.
+// ---------------------------------------------------
+//
+// codec framework is very feature rich.
+// When encoding or decoding into an interface, it depends on the runtime type of the interface.
+// The type of the interface may be a named type, an extension, etc.
+// Consequently, we fallback to runtime codec for encoding/decoding interfaces.
+// In addition, we fallback for any value which cannot be guaranteed at runtime.
+// This allows us support ANY value, including any named types, specifically those which
+// do not implement our interfaces (e.g. Selfer).
+//
+// This explains some slowness compared to other code generation codecs (e.g. msgp).
+// This reduction in speed is only seen when your refers to interfaces,
+// e.g. type T struct { A interface{}; B []interface{}; C map[string]interface{} }
+//
+// codecgen will panic if the file was generated with an old version of the library in use.
+//
+// Note:
+//   It was a conscious decision to have gen.go always explicitly call EncodeNil or TryDecodeAsNil.
+//   This way, there isn't a function call overhead just to see that we should not enter a block of code.
+
+// GenVersion is the current version of codecgen.
+//
+// NOTE: Increment this value each time codecgen changes fundamentally.
+// Fundamental changes are:
+//   - helper methods change (signature change, new ones added, some removed, etc)
+//   - codecgen command line changes
+//
+// v1: Initial Version
+// v2:
+// v3: Changes for Kubernetes:
+//     changes in signature of some unpublished helper methods and codecgen cmdline arguments.

+// Contains code shared by both encode and decode.
+
+// Some shared ideas around encoding/decoding
+// ------------------------------------------
+//
+// If an interface{} is passed, we first do a type assertion to see if it is
+// a primitive type or a map/slice of primitive types, and use a fastpath to handle it.
+//
+// If we start with a reflect.Value, we are already in reflect.Value land and
+// will try to grab the function for the underlying Type and directly call that function.
+// This is more performant than calling reflect.Value.Interface().
+//
+// This still helps us bypass many layers of reflection, and give best performance.
+//
+// Containers
+// ------------
+// Containers in the stream are either associative arrays (key-value pairs) or
+// regular arrays (indexed by incrementing integers).
+//
+// Some streams support indefinite-length containers, and use a breaking
+// byte-sequence to denote that the container has come to an end.
+//
+// Some streams also are text-based, and use explicit separators to denote the
+// end/beginning of different values.
+//
+// During encode, we use a high-level condition to determine how to iterate through
+// the container. That decision is based on whether the container is text-based (with
+// separators) or binary (without separators). If binary, we do not even call the
+// encoding of separators.
+//
+// During decode, we use a different high-level condition to determine how to iterate
+// through the containers. That decision is based on whether the stream contained
+// a length prefix, or if it used explicit breaks. If length-prefixed, we assume that
+// it has to be binary, and we do not even try to read separators.
+//
+// Philosophy
+// ------------
+// On decode, this codec will update containers appropriately:
+//    - If struct, update fields from stream into fields of struct.
+//      If field in stream not found in struct, handle appropriately (based on option).
+//      If a struct field has no corresponding value in the stream, leave it AS IS.
+//      If nil in stream, set value to nil/zero value.
+//    - If map, update map from stream.
+//      If the stream value is NIL, set the map to nil.
+//    - if slice, try to update up to length of array in stream.
+//      if container len is less than stream array length,
+//      and container cannot be expanded, handled (based on option).
+//      This means you can decode 4-element stream array into 1-element array.
+//
+// ------------------------------------
+// On encode, user can specify omitEmpty. This means that the value will be omitted
+// if the zero value. The problem may occur during decode, where omitted values do not affect
+// the value being decoded into. This means that if decoding into a struct with an
+// int field with current value=5, and the field is omitted in the stream, then after
+// decoding, the value will still be 5 (not 0).
+// omitEmpty only works if you guarantee that you always decode into zero-values.
+//
+// ------------------------------------
+// We could have truncated a map to remove keys not available in the stream,
+// or set values in the struct which are not in the stream to their zero values.
+// We decided against it because there is no efficient way to do it.
+// We may introduce it as an option later.
+// However, that will require enabling it for both runtime and code generation modes.
+//
+// To support truncate, we need to do 2 passes over the container:
+//   map
+//   - first collect all keys (e.g. in k1)
+//   - for each key in stream, mark k1 that the key should not be removed
+//   - after updating map, do second pass and call delete for all keys in k1 which are not marked
+//   struct:
+//   - for each field, track the *typeInfo s1
+//   - iterate through all s1, and for each one not marked, set value to zero
+//   - this involves checking the possible anonymous fields which are nil ptrs.
+//     too much work.
+//
+// ------------------------------------------
+// Error Handling is done within the library using panic.
+//
+// This way, the code doesn't have to keep checking if an error has happened,
+// and we don't have to keep sending the error value along with each call
+// or storing it in the En|Decoder and checking it constantly along the way.
+//
+// The disadvantage is that small functions which use panics cannot be inlined.
+// The code accounts for that by only using panics behind an interface;
+// since interface calls cannot be inlined, this is irrelevant.
+//
+// We considered storing the error is En|Decoder.
+//   - once it has its err field set, it cannot be used again.
+//   - panicing will be optional, controlled by const flag.
+//   - code should always check error first and return early.
+// We eventually decided against it as it makes the code clumsier to always
+// check for these error conditions.

+// EncodeTime encodes a time.Time as a []byte, including
+// information on the instant in time and UTC offset.
+//
+// Format Description
+//
+//   A timestamp is composed of 3 components:
+//
+//   - secs: signed integer representing seconds since unix epoch
+//   - nsces: unsigned integer representing fractional seconds as a
+//     nanosecond offset within secs, in the range 0 <= nsecs < 1e9
+//   - tz: signed integer representing timezone offset in minutes east of UTC,
+//     and a dst (daylight savings time) flag
+//
+//   When encoding a timestamp, the first byte is the descriptor, which
+//   defines which components are encoded and how many bytes are used to
+//   encode secs and nsecs components. *If secs/nsecs is 0 or tz is UTC, it
+//   is not encoded in the byte array explicitly*.
+//
+//       Descriptor 8 bits are of the form `A B C DDD EE`:
+//           A:   Is secs component encoded? 1 = true
+//           B:   Is nsecs component encoded? 1 = true
+//           C:   Is tz component encoded? 1 = true
+//           DDD: Number of extra bytes for secs (range 0-7).
+//                If A = 1, secs encoded in DDD+1 bytes.
+//                    If A = 0, secs is not encoded, and is assumed to be 0.
+//                    If A = 1, then we need at least 1 byte to encode secs.
+//                    DDD says the number of extra bytes beyond that 1.
+//                    E.g. if DDD=0, then secs is represented in 1 byte.
+//                         if DDD=2, then secs is represented in 3 bytes.
+//           EE:  Number of extra bytes for nsecs (range 0-3).
+//                If B = 1, nsecs encoded in EE+1 bytes (similar to secs/DDD above)
+//
+//   Following the descriptor bytes, subsequent bytes are:
+//
+//       secs component encoded in `DDD + 1` bytes (if A == 1)
+//       nsecs component encoded in `EE + 1` bytes (if B == 1)
+//       tz component encoded in 2 bytes (if C == 1)
+//
+//   secs and nsecs components are integers encoded in a BigEndian
+//   2-complement encoding format.
+//
+//   tz component is encoded as 2 bytes (16 bits). Most significant bit 15 to
+//   Least significant bit 0 are described below:
+//
+//       Timezone offset has a range of -12:00 to +14:00 (ie -720 to +840 minutes).
+//       Bit 15 = have\_dst: set to 1 if we set the dst flag.
+//       Bit 14 = dst\_on: set to 1 if dst is in effect at the time, or 0 if not.
+//       Bits 13..0 = timezone offset in minutes. It is a signed integer in Big Endian format.
