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.

func DefaultBytesSilent 

func DefaultBytesSilent(maxBytes int64, description ...string) *ProgressBar

DefaultBytesSilent is the same as DefaultBytes, but does not output anywhere. String() can be used to get the output instead.

func DefaultSilent 

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

DefaultSilent is the same as Default, but does not output anywhere. String() can be used to get the output instead.
