Base class for objects representing the various media file types that may include a thumbnail.
Objects of this class are comparable in terms of equality. Two objects of this class are
considered equal, if their :attr:`file_unique_id` is equal.
Args:
file_id (:obj:`str`): Identifier for this file, which can be used to download
or reuse the file.
file_unique_id (:obj:`str`): Unique identifier for this file, which
is supposed to be the same over time and for different bots.
Can't be used to download or reuse the file.
file_size (:obj:`int`, optional): File size.
thumb (:class:`telegram.PhotoSize`, optional): Thumbnail as defined by sender.
Attributes:
file_id (:obj:`str`): File identifier.
file_unique_id (:obj:`str`): Unique identifier for this file, which
is supposed to be the same over time and for different bots.
Can't be used to download or reuse the file.
file_size (:obj:`int`): Optional. File size.
