pub struct MetricsAspect { /* private fields */ }

Metrics aspect for collecting function call statistics.

Example

use aspect_std::MetricsAspect;
use aspect_macros::aspect;

let metrics = MetricsAspect::new();

#[aspect(metrics.clone())]
fn api_handler() -> Result<(), String> {
    Ok(())
}

// Print metrics
metrics.print();
