Async readiness traits. Useful when implementing async state machine internals, without directly relying on custom Futures structs. For example romio::TcpListener and romio::TcpStream.

Examples

Basic usage

#![feature(futures_api)]

use std::pin::Pin;
use std::task::{Poll, Waker};
use futures::prelude::*;
use std::io;

struct Fut;

impl Future for Fut {
  type Output = ();
  fn poll(self: Pin<&mut Self>, waker: &Waker) -> Poll<Self::Output> {
    Poll::Ready(())
  }
}

impl ready::Ready for Fut {
  type Ok = ();
  type Err = io::Error;
  fn poll_ready(&self, waker: &Waker)
    -> Poll<Result<Self::Ok, Self::Err>> {
    Poll::Ready(Ok(()))
  }
}

Installation

$ cargo add ready
