Trait async_serialization::AsyncWriterFuture

pub trait AsyncWriterFuture<W: AsyncWrite>: Future<Item = (W, usize), Error = (W, FutIoErr)> {
    fn already_written(&self) -> usize;
}

Deprecated

Base trait for futures that write things into AsyncWrites.

The future must yield a previously wrapped AsyncWrite, and the number of written bytes. If there's an error upon writing, the wrapped AsyncWrite is emitted together with the error.

Required Methods

fn already_written(&self) -> usize

Deprecated

Return how many bytes have already been written.
