Trait futures_util::stream::TryStream[][src]

pub trait TryStream: Stream + Sealed {
    type Ok;
    type Error;
    fn try_poll_next(
        self: Pin<&mut Self>,
        cx: &mut Context<'_>
    ) -> Poll<Option<Result<Self::Ok, Self::Error>>>; }
Expand description

A convenience for streams that return Result values that includes a variety of adapters tailored to such futures.

Associated Types

The type of successful values yielded by this future

The type of failures yielded by this future

Required methods

Poll this TryStream as if it were a Stream.

This method is a stopgap for a compiler limitation that prevents us from directly inheriting from the Stream trait; in the future it won’t be needed.
