It works in concert with the Go source code generated -for .proto files by the protocol compiler. - -A summary of the properties of the protocol buffer interface -for a protocol buffer variable v: - - - Names are turned from camel_case to CamelCase for export. - - There are no methods on v to set fields; just treat - them as structure fields. - - There are getters that return a field's value if set, - and return the field's default value if unset. - The getters work even if the receiver is a nil message. - - The zero value for a struct is its correct initialization state. - All desired fields must be set before marshaling. - - A Reset() method will restore a protobuf struct to its zero state. - - Non-repeated fields are pointers to the values; nil means unset. - That is, optional or required field int32 f becomes F *int32. - - Repeated fields are slices. - - Helper functions are available to aid the setting of fields. - msg.Foo = proto.String("hello") // set field - - Constants are defined to hold the default values of all fields that - have them. They have the form Default_StructName_FieldName. - Because the getter methods handle defaulted values, - direct use of these constants should be rare. - - Enums are given type names and maps from names to values. - Enum values are prefixed by the enclosing message's name, or by the - enum's type name if it is a top-level enum. Enum types have a String - method, and a Enum method to assist in message construction. - - Nested messages, groups and enums have type names prefixed with the name of - the surrounding message type. - - Extensions are given descriptor names that start with E_, - followed by an underscore-delimited list of the nested messages - that contain it (if any) followed by the CamelCased name of the - extension field itself. HasExtension, ClearExtension, GetExtension - and SetExtension are functions for manipulating extensions. - - Oneof field sets are given a single field in their message, - with distinguished wrapper types for each possible field value. - - Marshal and Unmarshal are functions to encode and decode the wire format. - -When the .proto file specifies `syntax="proto3"`, there are some differences: - - - Non-repeated fields of non-message type are values instead of pointers. - - Enum types do not get an Enum method. - -The simplest way to describe this is to see an example. -Given file test.proto, containing - - package example;
