Implementations§

§

impl<T, U> ProstCodec<T, U>

pub fn new() -> ProstCodec<T, U>

Configure a ProstCodec with encoder/decoder buffer settings. This is used to control how memory is allocated and grows per RPC.

§

impl<T, U> ProstCodec<T, U>
where T: Message + Send + 'static, U: Message + Default + Send + 'static,

pub fn raw_encoder( buffer_settings: BufferSettings, ) -> <ProstCodec<T, U> as Codec>::Encoder

A tool for building custom codecs based on prost encoding and decoding. See the codec_buffers example for one possible way to use this.

pub fn raw_decoder( buffer_settings: BufferSettings, ) -> <ProstCodec<T, U> as Codec>::Decoder

A tool for building custom codecs based on prost encoding and decoding. See the codec_buffers example for one possible way to use this.
