Function HandlerName

context/handler.go:145–162

HandlerName returns the handler's function name. See `Context.HandlerName` method to get function name of the current running handler in the chain. See `SetHandlerName` too.

(h interface{})

// See `Context.HandlerName` method to get function name of the current running handler in the chain.
// See `SetHandlerName` too.
func HandlerName(h interface{}) string {
	pc := valueOf(h).Pointer()
	fn := runtime.FuncForPC(pc)
	name := fn.Name()
	filename, _ := fn.FileLine(fn.Entry())
	filenameLower := strings.ToLower(filename)

	handlerNamesMu.RLock()
	for expr, newName := range handlerNames {
		if expr.MatchString(name) || expr.MatchFilename(filenameLower) {
			name = newName
			break
		}
	}
	handlerNamesMu.RUnlock()

	return trimHandlerName(name)
}

// HandlersNames returns a slice of "handlers" names
