Trait Encoder 

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

    // Required method
    fn encode(
        &self,
        item: Self::Item,
        dst: &mut BytesMut,
    ) -> Result<(), Self::Error>;

    // Provided method
    fn encode_vec(
        &self,
        item: Self::Item,
        dst: &mut BytesVec,
    ) -> Result<(), Self::Error> { ... }
}

Trait of helper objects to write out messages as bytes.

Required Associated Types

type Item

The type of items consumed by the Encoder

type Error: Debug

The type of encoding errors.

Required Methods

fn encode( &self, item: Self::Item, dst: &mut BytesMut, ) -> Result<(), Self::Error>

Encodes a frame into the buffer provided.

Provided Methods

fn encode_vec( &self, item: Self::Item, dst: &mut BytesVec, ) -> Result<(), Self::Error>

Encodes a frame into the buffer provided.
