Trait futures_util::stream::TryStream [−][src]
A convenience for streams that return Result
values that includes
a variety of adapters tailored to such futures.
Associated Types
type Ok
[src]
The type of successful values yielded by this future
type Error
[src]
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>>>
[src]
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.
