Module compression 

Per-message compression and grpc-accept-encoding negotiation.

Zstd uses its frame format, LZ4 uses a single standard frame (without legacy or skippable frames), Gzip uses RFC 1952, Deflate uses the RFC 1950 zlib wrapper, and Snappy uses its raw block format. Compression contexts are independent for each gRPC message.

Structs

CompressedMessage

Payload bytes and the value of the gRPC frame’s compressed flag.

CompressionConfig

Compression policy for outgoing and incoming messages.

Enums

CompressionAlgorithm

A supported value of the grpc-encoding header.

Constants

DEFAULT_MAX_DECODING_MESSAGE_SIZE

Maximum decoded message size accepted by the default configuration.

DEFAULT_MIN_COMPRESS_SIZE_BYTES

Messages smaller than this are sent without compression by default.

Functions

accept_encoding_header

Formats a comma-separated header, removing duplicate algorithms.

negotiate_compression

Selects the first locally preferred encoding explicitly accepted by a peer. Unknown tokens are ignored; identity is always available as the fallback. An absent header can be represented by an empty string. Parameters and wildcards are not part of the gRPC accept-encoding grammar.
