data Fields Source #

Type that represents meta information about fields of one constructor.

Constructors

Selectors [String]	Record constructor, containing the list of the selector names.
NoSelectors Int	Constructor with fields, but without selector names. The argument gives the number of fields.
NoFields	Constructor without fields.
