Trait Implementations

impl<T, EI, DO, R, W, FD: FnMut(DO) -> R, FE> Decoder for MapCodec<T, EI, DO, R, W, FD, FE>

where T: Decoder<Item = DO>,

type Error = <T as Decoder>::Error

The type of unrecoverable frame decoding errors.

type Item = R

The type of decoded frames.

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

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<T, EI, DO, R, W, FD, FE: FnMut(W) -> EI> Encoder<W> for MapCodec<T, EI, DO, R, W, FD, FE>

where T: Encoder<EI>,

type Error = <T as Encoder<EI>>::Error

The type of encoding errors.

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

Encodes a frame into the buffer provided.
