protosocket-prost

Protocol Buffers codec adapters for protosocket via prost.

Provides ProstSerializer and ProstDecoder, which implement the protosocket::Serialize and protosocket::Decoder traits for prost-generated types. Use them as the codec for any protosocket::Connection or protosocket-rpc service.

Wire format

Messages are framed using prost's length-delimited encoding: a varint byte-count prefix followed by the raw protobuf bytes.

Usage

use protosocket_prost::{ProstSerializer, ProstDecoder};
use protosocket::PooledEncoder;

// Encoder: wrap in PooledEncoder to reuse send buffers
type Encoder = PooledEncoder<ProstSerializer<MyRequest>>;
// Decoder
type Decoder = ProstDecoder<MyResponse>;

// Combine into a codec tuple for a protosocket Connection
let codec = (Encoder::default(), Decoder::default());

T must implement prost::Message (+ Default for the decoder).
