Module metrics 

Metrics hooks for observing handler activity.

Implement Metrics to receive callbacks on requests, responses, errors, and queue depth changes. The default no-op implementation can be overridden selectively.

Example

use a2a_protocol_server::metrics::Metrics;

struct MyMetrics;

impl Metrics for MyMetrics {
    fn on_request(&self, method: &str) {
        println!("request: {method}");
    }
}
