Trait async_codec::AsyncEncode

pub trait AsyncEncode where
    Self: Sized, {
    fn poll_encode<W: AsyncWrite>(
        self, 
        cx: &mut Context, 
        writer: &mut W
    ) -> PollEnc<Self>;
}

A trait for types that asynchronously encode into an AsyncWrite.

Required Methods

fn poll_encode<W: AsyncWrite>(
    self,
    cx: &mut Context,
    writer: &mut W
) -> PollEnc<Self>

Call writer.poll_write once with encoded data, propagating any Err and Pending, and returning how many bytes were written.

This consumes ownership of the encoder. If encoding did not terminate, the return value contains a new encoder that will resume at the correct point.

If writer.poll_write returns Ok(Ready(0)) even though the value has not been fully encoded, this must return an error of kind WriteZero.
