[−] Expand description

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[−]

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.
