You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: eventdescriptor.go
    path of file: ./repos/docker-ce/components/engine/vendor/github.com/Microsoft/go-winio/pkg/etw
    
    the code of the file until where you have to start completion: package etw

// Channel represents the ETW logging channel that is used. It can be used by
// event consumers to give an event special treatment.
type Channel uint8
    
func newEventDescriptor() *eventDescriptor {
	// Standard TraceLogging events default to the TraceLogging channel, and
	// verbose level.
	return &eventDescriptor{
		channel: ChannelTraceLogging,
		level:   LevelVerbose,
	}
}
