type ProgressBar

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

ProgressBar is a thread-safe, simple progress bar

func Default

func Default(max int64, description ...string) *ProgressBar

Default provides a progressbar with recommended defaults. Set max to -1 to use as a spinner.
