Enum async_codec::PollDec

pub enum PollDec<T, S, E> {
    Done(T, usize),
    Progress(S, usize),
    Pending(S),
    Errored(DecodeError<E>),
}

The return value for poll_decode.

Variants

Done(T, usize)

The decoder has run to completion, yielding an item of type T. The second value is the number of bytes that were read in the last call to poll_read.

Progress(S, usize)

Decoding is not done yet, but a non-zero number of bytes was read.

Pending(S)

Decoding can not make progress, because the reader would block. /// The current task is scheduled to be awoken when progress can be made.

Errored(DecodeError<E>)

An error occured during encoding.
