Trait Encoder

Source 
pub trait Encoder {
    type Item;
    type Error: From<Error>;

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

Trait of helper objects to write out messages as bytes, for use with FramedWrite.

Required Associated Types§

Source

type Item

The type of items consumed by the Encoder

Source

type Error: From<Error>

The type of encoding errors.

FramedWrite requires Encoders errors to implement From<io::Error> in the interest letting it return Errors directly.

Required Methods§

Source

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

Encodes a frame into the buffer provided.

This method will encode item into the byte buffer provided by dst. The dst provided is an internal buffer of the Framed instance and will be written out when possible.
