Trait Decoder 

pub trait Decoder {
    type Item;
    type Error: Debug;

    // Required method
    fn decode(
        &self,
        src: &mut BytesMut,
    ) -> Result<Option<Self::Item>, Self::Error>;
}

Decoding of frames via buffers.

Required Associated Types

type Item

The type of decoded frames.

type Error: Debug

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

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

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