Trait futures_core::future::IntoFuture

pub trait IntoFuture {
    type Future: Future<Item = Self::Item, Error = Self::Error>;
    type Item;
    type Error;
    fn into_future(self) -> Self::Future;
}

Types that can be converted into a future.

This trait is very similar to the IntoIterator trait.

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.
