Function CaptureMetricsFn

capture_metrics.go:37–41

CaptureMetricsFn wraps w and calls fn with the wrapped w and returns the resulting metrics. This is very similar to CaptureMetrics (which is just sugar on top of this func), but is a more usable interface if your application doesn't use the Go http.Handler interface.

(w http.ResponseWriter, fn func(http.ResponseWriter))

// sugar on top of this func), but is a more usable interface if your
// application doesn't use the Go http.Handler interface.
func CaptureMetricsFn(w http.ResponseWriter, fn func(http.ResponseWriter)) Metrics {
	m := Metrics{Code: http.StatusOK}
	m.CaptureMetrics(w, fn)
	return m
}

// CaptureMetrics wraps w and calls fn with the wrapped w and updates
// Metrics m with the resulting metrics. This is similar to CaptureMetricsFn,
