Expand description

A RequestResponseCodec defines the request and response types for a RequestResponse protocol or protocol family and how they are encoded / decoded on an I/O stream.

Associated Types

source

type Protocol: ProtocolName + Send + Clone

The type of protocol(s) or protocol versions being negotiated.

source

type Request: Send

The type of inbound and outbound requests.

source

type Response: Send

The type of inbound and outbound responses.

Required methods

source

fn read_request<'life0, 'life1, 'life2, 'async_trait, T>(
    &'life0 mut self,
