- GNU LESSER GENERAL PUBLIC LICENSE
- Version 3, 29 June 2007
-
- Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>
- Everyone is permitted to copy and distribute verbatim copies
- of this license document, but changing it is not allowed.
-
-
- This version of the GNU Lesser General Public License incorporates
-the terms and conditions of version 3 of the GNU General Public
-License, supplemented by the additional permissions listed below.
-
- 0. Additional Definitions.
-
- As used herein, "this License" refers to version 3 of the GNU Lesser
-General Public License, and the "GNU GPL" refers to version 3 of the GNU
-General Public License.
-
- "The Library" refers to a covered work governed by this License,
-other than an Application or a Combined Work as defined below.
-
- An "Application" is any work that makes use of an interface provided
-by the Library, but which is not otherwise based on the Library.
-Defining a subclass of a class defined by the Library is deemed a mode
-of using an interface provided by the Library.
-
- A "Combined Work" is a work produced by combining or linking an
-Application with the Library. The particular version of the Library
-with which the Combined Work was made is also called the "Linked
-Version".
-
- The "Minimal Corresponding Source" for a Combined Work means the
-Corresponding Source for the Combined Work, excluding any source code
-for portions of the Combined Work that, considered in isolation, are
-based on the Application, and not on the Linked Version.
-
- The "Corresponding Application Code" for a Combined Work means the
-object code and/or source code for the Application, including any data
-and utility programs needed for reproducing the Combined Work from the
-Application, but excluding the System Libraries of the Combined Work.
-
- 1. Exception to Section 3 of the GNU GPL.
-
- You may convey a covered work under sections 3 and 4 of this License
-without being bound by section 3 of the GNU GPL.
-
- 2. Conveying Modified Versions.
-
- If you modify a copy of the Library, and, in your modifications, a
-facility refers to a function or data to be supplied by an Application
-that uses the facility (other than as an argument passed when the
-facility is invoked), then you may convey a copy of the modified
-version:
-
- a) under this License, provided that you make a good faith effort to
- ensure that, in the event an Application does not supply the
- function or data, the facility still operates, and performs
- whatever part of its purpose remains meaningful, or
-
- b) under the GNU GPL, with none of the additional permissions of
- this License applicable to that copy.
-
- 3. Object Code Incorporating Material from Library Header Files.
-
- The object code form of an Application may incorporate material from
-a header file that is part of the Library. You may convey such object
-code under terms of your choice, provided that, if the incorporated
-material is not limited to numerical parameters, data structure
-layouts and accessors, or small macros, inline functions and templates
-(ten or fewer lines in length), you do both of the following:
-
- a) Give prominent notice with each copy of the object code that the
- Library is used in it and that the Library and its use are
- covered by this License.
-
- b) Accompany the object code with a copy of the GNU GPL and this license
- document.
-
- 4. Combined Works.
-
- You may convey a Combined Work under terms of your choice that,
-taken together, effectively do not restrict modification of the
-portions of the Library contained in the Combined Work and reverse
-engineering for debugging such modifications, if you also do each of
-the following:
-
- a) Give prominent notice with each copy of the Combined Work that
- the Library is used in it and that the Library and its use are
- covered by this License.
-
- b) Accompany the Combined Work with a copy of the GNU GPL and this license
- document.
-
- c) For a Combined Work that displays copyright notices during
- execution, include the copyright notice for the Library among
- these notices, as well as a reference directing the user to the
- copies of the GNU GPL and this license document.
-
- d) Do one of the following:
-
- 0) Convey the Minimal Corresponding Source under the terms of this
- License, and the Corresponding Application Code in a form
- suitable for, and under terms that permit, the user to
- recombine or relink the Application with a modified version of
- the Linked Version to produce a modified Combined Work, in the
- manner specified by section 6 of the GNU GPL for conveying
- Corresponding Source.
-
- 1) Use a suitable shared library mechanism for linking with the
- Library. A suitable mechanism is one that (a) uses at run time
- a copy of the Library already present on the user's computer
- system, and (b) will operate properly with a modified version
- of the Library that is interface-compatible with the Linked
- Version.
-
- e) Provide Installation Information, but only if you would otherwise
- be required to provide such information under section 6 of the
- GNU GPL, and only to the extent that such information is
- necessary to install and execute a modified version of the
- Combined Work produced by recombining or relinking the
- Application with a modified version of the Linked Version. (If
- you use option 4d0, the Installation Information must accompany
- the Minimal Corresponding Source and Corresponding Application
- Code. If you use option 4d1, you must provide the Installation
- Information in the manner specified by section 6 of the GNU GPL
- for conveying Corresponding Source.)
-
- 5. Combined Libraries.
-
- You may place library facilities that are a work based on the
-Library side by side in a single library together with other library
-facilities that are not Applications and are not covered by this
-License, and convey such a combined library under terms of your
-choice, if you do both of the following:
-
- a) Accompany the combined library with a copy of the same work based
- on the Library, uncombined with any other library facilities,
- conveyed under the terms of this License.
-
- b) Give prominent notice with the combined library that part of it
- is a work based on the Library, and explaining where to find the
- accompanying uncombined form of the same work.
-
- 6. Revised Versions of the GNU Lesser General Public License.
-
- The Free Software Foundation may publish revised and/or new versions
-of the GNU Lesser General Public License from time to time. Such new
-versions will be similar in spirit to the present version, but may
-differ in detail to address new problems or concerns.
-
- Each version is given a distinguishing version number. If the
-Library as you received it specifies that a certain numbered version
-of the GNU Lesser General Public License "or any later version"
-applies to it, you have the option of following the terms and
-conditions either of that published version or of any later version
-published by the Free Software Foundation. If the Library as you
-received it does not specify a version number of the GNU Lesser
-General Public License, you may choose any version of the GNU Lesser
-General Public License ever published by the Free Software Foundation.
-
- If the Library as you received it specifies that a proxy can decide
-whether future versions of the GNU Lesser General Public License shall
-apply, that proxy's public statement of acceptance of any version is
-permanent authorization for you to choose that version for the
-Library.

-# ratelimit
---
- import "github.com/juju/ratelimit"
-
-The ratelimit package provides an efficient token bucket implementation. See
-http://en.wikipedia.org/wiki/Token_bucket.
-
-## Usage
-
-#### func Reader
-
-```go
-func Reader(r io.Reader, bucket *Bucket) io.Reader
-```
-Reader returns a reader that is rate limited by the given token bucket. Each
-token in the bucket represents one byte.
-
-#### func Writer
-
-```go
-func Writer(w io.Writer, bucket *Bucket) io.Writer
-```
-Writer returns a writer that is rate limited by the given token bucket. Each
-token in the bucket represents one byte.
-
-#### type Bucket
-
-```go
-type Bucket struct {
-}
-```
-
-Bucket represents a token bucket that fills at a predetermined rate. Methods on
-Bucket may be called concurrently.
-
-#### func NewBucket
-
-```go
-func NewBucket(fillInterval time.Duration, capacity int64) *Bucket
-```
-NewBucket returns a new token bucket that fills at the rate of one token every
-fillInterval, up to the given maximum capacity. Both arguments must be positive.
-The bucket is initially full.
-
-#### func NewBucketWithQuantum
-
-```go
-func NewBucketWithQuantum(fillInterval time.Duration, capacity, quantum int64) *Bucket
-```
-NewBucketWithQuantum is similar to NewBucket, but allows the specification of
-the quantum size - quantum tokens are added every fillInterval.
-
-#### func NewBucketWithRate
-
-```go
-func NewBucketWithRate(rate float64, capacity int64) *Bucket
-```
-NewBucketWithRate returns a token bucket that fills the bucket at the rate of
-rate tokens per second up to the given maximum capacity. Because of limited
-clock resolution, at high rates, the actual rate may be up to 1% different from
-the specified rate.
-
-#### func (*Bucket) Rate
-
-```go
-func (tb *Bucket) Rate() float64
-```
-Rate returns the fill rate of the bucket, in tokens per second.
-
-#### func (*Bucket) Take
-
-```go
-func (tb *Bucket) Take(count int64) time.Duration
-```
-Take takes count tokens from the bucket without blocking. It returns the time
-that the caller should wait until the tokens are actually available.
-
-Note that if the request is irrevocable - there is no way to return tokens to
-the bucket once this method commits us to taking them.
-
-#### func (*Bucket) TakeAvailable
-
-```go
-func (tb *Bucket) TakeAvailable(count int64) int64
-```
-TakeAvailable takes up to count immediately available tokens from the bucket. It
-returns the number of tokens removed, or zero if there are no available tokens.
-It does not block.
-
-#### func (*Bucket) TakeMaxDuration
-
-```go
-func (tb *Bucket) TakeMaxDuration(count int64, maxWait time.Duration) (time.Duration, bool)
-```
-TakeMaxDuration is like Take, except that it will only take tokens from the
-bucket if the wait time for the tokens is no greater than maxWait.
-
-If it would take longer than maxWait for the tokens to become available, it does
-nothing and reports false, otherwise it returns the time that the caller should
-wait until the tokens are actually available, and reports true.
-
-#### func (*Bucket) Wait
-
-```go
-func (tb *Bucket) Wait(count int64)
-```
-Wait takes count tokens from the bucket, waiting until they are available.
-
-#### func (*Bucket) WaitMaxDuration
-
-```go
-func (tb *Bucket) WaitMaxDuration(count int64, maxWait time.Duration) bool
-```
-WaitMaxDuration is like Wait except that it will only take tokens from the
-bucket if it needs to wait for no greater than maxWait. It reports whether any
-tokens have been removed from the bucket If no tokens have been removed, it
-returns immediately.
