Macro assert_next_with_timeout

macro_rules! assert_next_with_timeout {
    ($stream:expr) => { ... };
    ($stream:expr, $timeout_ms:expr) => { ... };
}

Available on crate feature testing only.

Asserts that the next item in a Stream is received within a given timeout.

This macro waits for the next item from an asynchronous Stream or, if no item is received within the specified timeout, the macro panics.

Parameters

• $stream: The Stream or Subscriber to poll for the next item.
• $timeout_ms (optional): The timeout in milliseconds to wait for the next item. Defaults to 500ms if not provided.

Example

use futures_util::{stream, StreamExt};
use matrix_sdk::assert_next_with_timeout;

let mut stream = stream::iter(vec![1, 2, 3]);
let next_item = assert_next_with_timeout!(stream, 1000); // Waits up to 1000ms
assert_eq!(next_item, 1);

// The timeout can be omitted, in which case it defaults to 500 ms.
let next_item = assert_next_with_timeout!(stream); // Waits up to 500ms
assert_eq!(next_item, 2);
