Module metrics 

Metrics hooks for observing handler activity.

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

Example

use a2a_protocol_server::metrics::Metrics;
use std::time::Duration;

struct MyMetrics;

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

Structs
