// OnProgress is an event that is fired when progress has been made on the
// download. Four arguments are passed to the listener:
//
// `name`: A string identifying the item being downloaded.
//
// `progress`: An int64 indicating the amount of bytes downloaded so far.
//
// `total`: An int64 indicating the total size of the download. This may be
// -1, indicating an unknown size.
//
// `err`: An error, if one has occurred. If the download is finished, the
// error will be io.EOF. If the download was closed before it was finished,
// the error will be ErrClosed.
