1/// Asserts that the mock handle receives a new request equal to the given
2/// value.
3///
4/// On success, the [`SendResponse`] handle for the matched request is returned,
5/// allowing the caller to respond to the request. On failure, the macro panics.
6///
7/// # Examples
8///
9/// ```rust
10/// use tower_service::Service;
11/// use tower_test::{mock, assert_request_eq};
12/// use tokio_test::assert_ready;
13///
14/// # async fn test() {
15/// let (mut service, mut handle) = mock::spawn();
16///
17/// assert_ready!(service.poll_ready());
18///
19/// let response = service.call("hello");
20///
21/// assert_request_eq!(handle, "hello").send_response("world");
22///
23/// assert_eq!(response.await.unwrap(), "world");
24/// # }
25/// ```
