Trait Sleep

pub trait Sleep {
    type Poll: Future;

    // Required method
    fn next_poll(&mut self) -> Self::Poll;
}

Governs the behaviour of of polling in async functions.

There is a generic implementation for any function retuning a future. This allows e.g. to pass || tokio::time::sleep(Duration::from_millis(50)) to functions expecting sleep. That is if you use tokio as your async runtime, of course.

Required Associated Types

type Poll: Future

Required Methods

fn next_poll(&mut self) -> Self::Poll
