Trait valuable_futures::Future

pub trait Future: Sized {
    type Item;
    type Error;
    fn poll(self) -> Result<Async<Self::Item, Self>, Self::Error>;

    fn into_future(self) -> FutureWrapper<Self> { ... }
}

A type-safe future trait

Associated Types

type Item

The type of value that this future will resolved with if it is successful

type Error

The type of error that this future will resolve with if it fails in a normal fashion.

Required Methods

fn poll(self) -> Result<Async<Self::Item, Self>, Self::Error>

Query this future to see if its value has become available, registering interest if it is not.

The only difference of this method to the futures::Future::poll is that self is passed by value.

See documentation of futures for more more information on how the method should be implemented.

Provided Methods

fn into_future(self) -> FutureWrapper<Self>

Convert this object into futures::Future
