func WithProgress

func WithProgress(writer io.Writer, reader io.Reader, logger *logger.Logger, prefix string) error

WithProgress implements io.Copy with a buffered reader, then measures progress throughout the copy process. The buffer is set at a reasonable size for reasonable performance. On error, if io.EOF is not returned then the error is returned. Otherwise, it is nil.
