fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

type Item = ByteRecord

A framed record, not yet deserialised. Errors here are framing errors and are terminal.

type Error = StreamError

The type of unrecoverable frame decoding errors.

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

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

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

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.
