Expand description

Asserts if a poll is ready and check for equality on the value

This will invoke panic! if the provided Poll does not evaluate to Poll::Ready at runtime and the value produced does not partially equal the expected value.

§Custom Messages

This macro has a second form, where a custom panic message can be provided with or without arguments for formatting.

§Examples

use futures_util::future;
use tokio_test::{assert_ready_eq, task};

let mut fut = task::spawn(future::ready(42));
assert_ready_eq!(fut.poll(), 42);
