Trait cosmic::iced_futures::futures::TryFuture

pub trait TryFuture: Future + Sealed {
    type Ok;
    type Error;

    // Required method
    fn try_poll(
        self: Pin<&mut Self>,
        cx: &mut Context<'_>,
    ) -> Poll<Result<Self::Ok, Self::Error>>;
}

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

Required 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>>

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.

Implementors

impl<F, T, E> TryFuture for F
