Create a new RPC codec

Trait Implementations

impl Decoder for RpcCodec

type Item = RpcRequest

The type of decoded frames.

type Error = ControllerError

The type of unrecoverable frame decoding errors.

fn decode(&mut self, src: &mut BytesMut) -> Result<Option<Self::Item>>

Attempts to decode a frame from the provided buffer of bytes.

fn decode_eof( &mut self, buf: &mut BytesMut, ) -> Result<Option<Self::Item>, Self::Error>

A default method available to be called when there are no more bytes available to be read from the underlying I/O.

fn framed<T>(self, io: T) -> Framed<T, Self>

where T: AsyncRead + AsyncWrite, Self: Sized,

Provides a Stream and Sink interface for reading and writing to this Io object, using Decode and Encode to read and write the raw data.

impl Default for RpcCodec

fn default() -> Self

Returns the “default value” for a type.

impl Encoder<RpcResponse> for RpcCodec

type Error = ControllerError

The type of encoding errors.

fn encode(&mut self, item: RpcResponse, dst: &mut BytesMut) -> Result<()>

Encodes a frame into the buffer provided.
