	DDTraceEnabled  bool

func (*Listener) HandlerFinished 

func (l *Listener) HandlerFinished(ctx context.Context)

func (*Listener) HandlerStarted 

func (l *Listener) HandlerStarted(ctx context.Context, msg json.RawMessage) context.Context

HandlerStarted creates the function execution span representing the Lambda function execution and adds that span to the context so that the user can create child spans (if Datadog tracing is enabled)
