In particular, it is an error to call StartWork and not call End(...) on the returned WorkDone handle.

The progress item is considered cancellable if the given cancel func is non-nil.

Example:

func Generate(ctx) (err error) {
  ctx, cancel := context.WithCancel(ctx)
  defer cancel()
  work := s.StartWork(ctx, "generate", "running go generate", cancel)
  defer func() {
    if err != nil {
      work.End(ctx, fmt.Sprintf("generate failed: %v", err))

type WorkDone Uses

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

WorkDone represents a unit of work that is reported to the client via the progress API.

func (*WorkDone) End Uses

func (wd *WorkDone) End(ctx context.Context, message string) error

End reports a workdone completion back to the client.

func (*WorkDone) Progress Uses

func (wd *WorkDone) Progress(ctx context.Context, message string, percentage float64) error
