Function init_in_memory_tracing 

pub fn init_in_memory_tracing() -> InMemoryTracingGuard

Initialize in-memory tracing for unit tests

Important

Tests using this function MUST be marked with #[serial] since they share global state through init_event_dispatch.

Example

use micromegas_tracing::test_utils::init_in_memory_tracing;
use serial_test::serial;

// In your test file:
// #[test]
// #[serial]
fn test_example() {
    let guard = init_in_memory_tracing();
    // Use tracing macros: info!(), debug!(), span_scope!(), etc.
    // Verify results in guard.sink.state
    // Automatic cleanup when guard is dropped
}
