Trait Decoder 

pub trait Decoder {
    type Item;
    type Error: Error + 'static;

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

    // Provided method
    fn decode_eof(
        &mut self,
        src: &mut BytesMut,
    ) -> Result<Option<Self::Item>, Self::Error> { ... }
}

Required Associated Types

type Item

type Error: Error + 'static

Required Methods

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

Provided Methods

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

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
