Expand description

Backend-neutral hook for recording HTTP request metrics.

Implement this trait to bridge Nidus’ middleware lifecycle into a concrete metrics backend. Hooks are called in-process: one on_request before the inner service, one on_response after a response, or on_error if the inner service returns an error before producing a response.

Required Methods§

Source

fn on_request(&self, method: &Method, route: Option<&str>)

Records that a request entered the service.

Source

fn on_response( &self, method: &Method, route: Option<&str>, status: StatusCode, latency: Duration, )

Records that a response left the service.

Provided Methods§

Source

fn on_error(&self, _method: &Method, _route: Option<&str>, _latency: Duration)

Records that the inner service returned an error before producing a response.

Dyn Compatibility§

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
