Trait heim_common::prelude::futures::stream::TryStream

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

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

type Error

The type of failures yielded by this future

Required methods

pub fn try_poll_next(
    self: Pin<&mut Self>,
    cx: &mut Context<'_>
) -> Poll<Option<Result<Self::Ok, Self::Error>>>

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.
