Package encoding defines the interface for the compressor and codec, and
functions to register and retrieve compressors and codecs.

later release.

Package-Level Type Names (total 3, all are exported)
Codec defines the interface gRPC uses to encode and decode messages. Note
that implementations of this interface must be thread safe; a Codec's
methods can be called from concurrent goroutines.
Marshal returns the wire format of v.
Name returns the name of the Codec implementation. The returned string
will be used as part of content type in transmission. The result must be
static; the result cannot change between calls.
Unmarshal parses the wire format into v.
func GetCodec(contentSubtype string) Codec
func RegisterCodec(codec Codec)
func google.golang.org/grpc.ForceCodec(codec Codec) grpc.CallOption
func google.golang.org/grpc.ForceServerCodec(codec Codec) grpc.ServerOption
func google.golang.org/grpc.newCodecV1Bridge(c Codec) CodecV2
CodecV2 defines the interface gRPC uses to encode and decode messages. Note
that implementations of this interface must be thread safe; a CodecV2's
methods can be called from concurrent goroutines.
Marshal returns the wire format of v. The buffers in the returned
[mem.BufferSlice] must have at least one reference each, which will be freed
by gRPC when they are no longer needed.
Name returns the name of the Codec implementation. The returned string
will be used as part of content type in transmission. The result must be
static; the result cannot change between calls.
Unmarshal parses the wire format into v. Note that data will be freed as soon
as this function returns. If the codec wishes to guarantee access to the data
after this function, it must take its own reference that it frees when it is
no longer needed.

Compressor is used for compressing and decompressing when sending or
receiving messages.
If a Compressor implements `DecompressedSize(compressedBytes []byte) int`,
gRPC will invoke it to determine the size of the buffer allocated for the
result of decompression. A return value of -1 indicates unknown size.
Compress writes the data written to wc to w after compressing it. If an
error occurs while initializing the compressor, that error is returned
instead.
Decompress reads data from r, decompresses it, and provides the
uncompressed data via the returned io.Reader. If an error occurs while
initializing the decompressor, that error is returned instead.
Name is the name of the compression codec and is used to set the content
coding header. The result must be static; the result cannot change
between calls.

Package-Level Functions (total 6, all are exported)
GetCodec gets a registered Codec by content-subtype, or nil if no Codec is
registered for the content-subtype.
The content-subtype is expected to be lowercase.
GetCodecV2 gets a registered CodecV2 by content-subtype, or nil if no CodecV2 is
registered for the content-subtype.
The content-subtype is expected to be lowercase.
GetCompressor returns Compressor for the given compressor name.
RegisterCodec registers the provided Codec for use with all gRPC clients and
servers.
The Codec will be stored and looked up by result of its Name() method, which
should match the content-subtype of the encoding handled by the Codec. This
is case-insensitive, and is stored and looked up as lowercase. If the
result of calling Name() is an empty string, RegisterCodec will panic. See
Content-Type on
https://github.com/grpc/grpc/blob/master/doc/PROTOCOL-HTTP2.md#requests for
more details.
NOTE: this function must only be called during initialization time (i.e. in
an init() function), and is not thread-safe. If multiple Codecs are
registered with the same name, the one registered last will take effect.
RegisterCodecV2 registers the provided CodecV2 for use with all gRPC clients and
servers.
The CodecV2 will be stored and looked up by result of its Name() method, which
should match the content-subtype of the encoding handled by the CodecV2. This
is case-insensitive, and is stored and looked up as lowercase. If the
result of calling Name() is an empty string, RegisterCodecV2 will panic. See
Content-Type on
https://github.com/grpc/grpc/blob/master/doc/PROTOCOL-HTTP2.md#requests for
more details.
If both a Codec and CodecV2 are registered with the same name, the CodecV2
will be used.
NOTE: this function must only be called during initialization time (i.e. in
an init() function), and is not thread-safe. If multiple Codecs are
registered with the same name, the one registered last will take effect.
RegisterCompressor registers the compressor with gRPC by its name. It can
be activated when sending an RPC via grpc.UseCompressor(). It will be
automatically accessed when receiving a message based on the content coding
header. Servers also use it to send a response with the same encoding as
the request.
NOTE: this function must only be called during initialization time (i.e. in
an init() function), and is not thread-safe. If multiple Compressors are
registered with the same name, the one registered last will take effect.

Identity specifies the optional encoding for uncompressed streams.
It is intended for grpc internal use only.
