Trait Waitable

pub trait Waitable {
    type Output;

    // Required method
    fn wait(self) -> Self::Output
       where Self: Sized;
}

The Waitable trait defines a method that is implemented for all Future types. This allows you to call the .wait() method on any Future outside of an async context.

Required Associated Types

type Output

Required Methods

fn wait(self) -> Self::Output

where Self: Sized,

Implementors

impl<F> Waitable for F

where F: Future,

This is the implementation of the Waitable trait for every Future. All async functions return a Future, so this attaches the .wait() method to every async function.

All it does is put the thread to sleep until the Future is ready to return a value.

type Output = <F as Future>::Output
