Required Methods§

fn on_response(self, response: &Response, 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.
