Required Methods

fn on_response(self, response: &Response<B>, latency: Duration, span: &Span)

Do the thing.

latency is the duration since the request was received.

span is the tracing Span, corresponding to this request, produced by the closure passed to TraceLayer::make_span_with. It can be used to record field values that weren’t known when the span was created.

Dyn Compatibility

This trait is dyn compatible.

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