Decodes gRPC message types

Required Associated Types

type Item

The type that is decoded.

type Error: From<Error>

The type of unrecoverable frame decoding errors.

Required Methods

fn decode( &mut self, src: &mut DecodeBuf<'_>, ) -> Result<Option<Self::Item>, Self::Error>

Decode a message from the buffer.

The buffer will contain exactly the bytes of a full message. There is no need to get the length from the bytes, gRPC framing is handled for you.

Provided Methods

fn buffer_settings(&self) -> BufferSettings

Controls how rama-grpc creates and expands decode buffers.
