Expand description

Assert an expression is Ready(_).

  • If true, return ().

  • Otherwise, call panic! with a message and the values of the expressions with their debug representations.

§Examples

use std::task::Poll;
use std::task::Poll::*;
let a: Poll<i8> = Ready(1);
assert_poll_ready!(a);

let a: Poll<i8> = Pending;
assert_poll_ready!(a);
// assertion failed: `assert_poll_ready!(a)`
// https://docs.rs/assertables/8.7.0/assertables/macro.assert_poll_ready.html
//  a label: `a`,
//  a debug: `Pending`
