Expand description

Decoding of frames via buffers.

Associated Types

The type of decoded frames.

The type of unrecoverable frame decoding errors.

If an individual message is ill-formed but can be ignored without interfering with the processing of future messages, it may be more useful to report the failure as an Item.

Required methods

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

Provided methods

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

This method defaults to calling decode and returns an error if Ok(None) is returned while there is unconsumed data in buf. Typically this doesn’t need to be implemented unless the framing protocol differs near the end of the stream.
