Trait heim_common::prelude::futures::future::TryFuture

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

Associated Types

The type of successful values yielded by this future

type Error

Required methods

pub 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.
