This module contains constructors for expectations defined in the event, span, and field modules.

Examples

let (collector, handle) = collector::mock()
    // Expect an event with message
    .event(expect::event().with_fields(expect::msg("message")))
    .only()
    .run_with_handle();

tracing::collect::with_default(collector, || {
    tracing::info!("message");
});

handle.assert_finished();
