Examples
fn handle_request() { let start = Instant::now(); process(); let end = Instant::now(); // We can pass instances of `Instant` directly: timing!("performance.request_processed", start, end); // Or we can pass just the delta: let delta = end - start; timing!("performance.request_processed", delta); // And we can even pass unsigned values, both for the start/end notation: let start: u64 = 100; let end: u64 = 200; timing!("performance.request_processed", start, end); // And the delta notation: let delta: u64 = end - start; timing!("performance.request_processed", delta); }
