def __init__(self, name, default, enum, fmt="H"):
""" Initializes enum fields.
@param name: name of this field
@param default: default value of this field
@param enum: either a dict or a tuple of two callables. Dict keys are # noqa: E501
the internal values, while the dict values are the
user-friendly representations. If the tuple is provided, # noqa: E501
the first callable receives the internal value as
parameter and returns the user-friendly representation
and the second callable does the converse. The first
callable may return None to default to a literal string
(repr()) representation.
@param fmt: struct.pack format used to parse and serialize the
internal value from and to machine representation.
