[][src]Trait futures::future::IntoFuture

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

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.
