Function ufut::poll_state

pub fn poll_state<F, S, T>(state: S, fun: F) -> PollState<F, S> where
    F: FnMut(&mut S, &mut Context<'_>) -> Poll<T>, 

Creates a future from a function returning Poll that has access to a provided state value.

Examples

use futures_lite::future::block_on;
use futures_micro::poll_state;
use std::task::{Context, Poll};

fn f(state: &mut i32, _ctx: &mut Context<'_>) -> Poll<i32> {
    Poll::Ready(*state + 1)
}

assert_eq!(poll_state(7, f).await, 8);
