Functions ¶

func Flow ¶

func Flow(ctx context.Context, from *Span, to *Span)

Flow marks a flow indicating that the 'to' span depends on the 'from' span. Flow should be called while the 'to' span is in progress.

func Start ¶

func Start(ctx context.Context, file string) (context.Context, func() error, error)

Start starts a trace which writes to the given file.

func StartGoroutine ¶

func StartGoroutine(ctx context.Context) context.Context

StartGoroutine associates the context with a new Thread ID. The Chrome trace viewer associates each trace event with a thread, and doesn't expect events with the same thread id to happen at the same time.

Types ¶

type Span ¶

type Span struct {
	// contains filtered or unexported fields
}

func StartSpan ¶

func StartSpan(ctx context.Context, name string) (context.Context, *Span)

StartSpan starts a trace event with the given name. The Span ends when its Done method is called.

func (*Span) Done ¶

func (s *Span) Done()
