Trait Encoder

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

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

Encoding of messages as bytes, for use with FramedWrite.

Required Associated Types

type Item<'a>

The type of items consumed by encode

type Error: From<Error>

The type of encoding errors.

Required Methods

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

Encodes an item into the BytesMut provided by dst.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
