Documentation
type ValueEnumeration = IEnumeration Value Source #
Base types
enumVoid :: ValueEnumeration Source #
Enumerate all values of type Void (none).
enumUnit :: ValueEnumeration Source #
Enumerate all values of type Unit (the single value unit).
enumBool :: ValueEnumeration Source #
Enumerate the values of type Bool as [false, true].
enumN :: ValueEnumeration Source #
Enumerate all values of type Nat (0, 1, 2, ...).
enumZ :: ValueEnumeration Source #
Enumerate all values of type Integer (0, 1, -1, 2, -2, ...).
enumF :: ValueEnumeration Source #
Enumerate all values of type Fractional in the Calkin-Wilf
order (1, 12, 2, 13, 32, 23, 3, ...).
enumQ :: ValueEnumeration Source #
Enumerate all values of type Rational in the Calkin-Wilf order,
with negatives interleaved (0, 1, -1, 12, -12, 2, -2, ...).
enumC :: ValueEnumeration Source #
Enumerate all Unicode characters.
Containers
enumSet :: ValueEnumeration -> ValueEnumeration Source #
Enumerate all *finite* sets over a certain element type, given an enumeration of the elements. If we think of each finite set as a binary string indicating which elements in the enumeration are members, the sets are enumerated in order of the binary strings.
enumList :: ValueEnumeration -> ValueEnumeration Source #
Enumerate all *finite* lists over a certain element type, given an enumeration of the elements. It is very difficult to describe the order in which the lists are generated.
Any type
enumType :: Type -> ValueEnumeration Source #
Enumerate the values of a given type.
Lifted functions that return lists
enumerateType :: Type -> [Value] Source #
Produce an actual list of the values of a type.
enumerateTypes :: [Type] -> [[Value]] Source #
Produce an actual list of values enumerated from a finite product of types.
