Struct TopiqCodec 

pub struct TopiqCodec { /* private fields */ }

Codec for encoding/decoding Frame values on the wire.

Wire format: [4B frame body length (big-endian)][1B version][N bytes msgpack Frame]

The 4-byte length covers the version byte + msgpack body.

Trait Implementations

impl Decoder for TopiqCodec

type Item = Frame

The type of decoded frames.

type Error = TopiqError

The type of unrecoverable frame decoding errors.

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

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 Encoder<Frame> for TopiqCodec

type Error = TopiqError

The type of encoding errors.

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

Encodes a frame into the buffer provided.
