Implementations§

source §

impl<T> Ready<T>

source

pub fn into_inner(self) -> T

🔬This is a nightly-only experimental API. (ready_into_inner)

Consumes the Ready, returning the wrapped value.

§Panics

Will panic if this Ready was already polled to completion.

§Examples

#![feature(ready_into_inner)]
use std::future;

let a = future::ready(1);
assert_eq!(a.into_inner(), 1);
