[−][src]Trait futures::prelude::TryFuture
A convenience for futures that return Result
values that includes
a variety of adapters tailored to such futures.
Associated Types
type Ok
The type of successful values yielded by this future
type Error
The type of failures yielded by this future
Required methods
fn try_poll(
self: Pin<&mut Self>,
cx: &mut Context
) -> Poll<Result<Self::Ok, Self::Error>>
self: Pin<&mut Self>,
cx: &mut Context
) -> Poll<Result<Self::Ok, Self::Error>>
Poll this TryFuture
as if it were a Future
.
This method is a stopgap for a compiler limitation that prevents us from
directly inheriting from the Future
trait; in the future it won't be
needed.
