Trait Implementations

impl Decoder for Codec

type Item = FrontendMessage

The type of decoded frames.

type Error = Error

The type of unrecoverable frame decoding errors.

fn decode( &mut self, src: &mut BytesMut ) -> Result<Option<FrontendMessage>, 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 Default for Codec

fn default() -> Codec

Returns the “default value” for a type.

impl Encoder<BackendMessage> for Codec

type Error = Error

The type of encoding errors.

fn encode( &mut self, msg: BackendMessage, dst: &mut BytesMut ) -> Result<(), Error>

Encodes a frame into the buffer provided.
