async-ready

Async readiness traits. Useful when implementing async state machines that can later be wrapped in dedicated futures.

Examples

Basic usage ```rust

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

struct Fut;

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

impl AsyncReady for Fut { type Ok = (); type Err = io::Error;

fn poll_ready(&mut self, waker: &Waker) -> Poll> { Poll::Ready(Ok(())) } } ```

sh $ cargo add async-ready
