Macro lib::assert_poll_ready

macro_rules! assert_poll_ready {
    ($poll:expr $(,)?) => { ... };
    ($poll:expr, $($message:tt)+) => { ... };
}

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)`
//  a label: `a`,
//  a debug: `Pending`
