Trait IntoFuture

pub trait IntoFuture {
    type Future: Future<Item = Self::Item, Error = Self::Error>;
    type Item;
    type Error;

    // Required method
    fn into_future(self) -> Self::Future;
}

Class of types which can be converted into a future.

This trait is very similar to the IntoIterator trait and is intended to be used in a very similar fashion.

Required Associated Types

type Future: Future<Item = Self::Item, Error = Self::Error>

The future that this type can be converted into.

type Item

The item that the future may resolve with.

type Error

The error that the future may resolve with.

Required Methods

fn into_future(self) -> Self::Future

Consumes this object and produces a future.
