1. fromNumber :: C a => a -> T a

   non-negative	Numeric.NonNegative.Chunky

   No documentation available.

2. toNumber :: C a => T a -> a

   non-negative	Numeric.NonNegative.Chunky

   No documentation available.

3. fromNumber :: (Ord a, Num a) => a -> T a

   non-negative	Numeric.NonNegative.Wrapper

   Convert a number to a non-negative number. If a negative number is given, an error is raised.

4. fromNumberClip :: (Ord a, Num a) => a -> T a

   non-negative	Numeric.NonNegative.Wrapper

   Convert a number to a non-negative number. A negative number will be replaced by zero. Use this function with care since it may hide bugs.

5. fromNumberMsg :: (Ord a, Num a) => String -> a -> T a

   non-negative	Numeric.NonNegative.Wrapper

   No documentation available.

6. fromNumberUnsafe :: a -> T a

   non-negative	Numeric.NonNegative.Wrapper

   Wrap a number into a non-negative number without doing checks. This routine exists entirely for efficiency reasons and must be used only in cases where you are absolutely sure, that the input number is non-negative.

7. toNumber :: T a -> a

   non-negative	Numeric.NonNegative.Wrapper

   No documentation available.

8. boundedEnumLaws :: (Enum a, Bounded a, Eq a, Arbitrary a, Show a) => Proxy a -> Laws

   quickcheck-classes-base	Test.QuickCheck.Classes.Base

   Tests the same properties as enumLaws except that it requires the type to have a Bounded instance. These tests avoid taking the successor of the maximum element or the predecessor of the minimal element.

9. enumLaws :: (Enum a, Eq a, Arbitrary a, Show a) => Proxy a -> Laws

   quickcheck-classes-base	Test.QuickCheck.Classes.Base

   Tests the following properties:

   • Succ Pred Identity succ (pred x) ≡ x
   • Pred Succ Identity pred (succ x) ≡ x
   This only works for Enum types that are not bounded, meaning that succ and pred must be total. This means that these property tests work correctly for types like Integer but not for Int. Sadly, there is not a good way to test fromEnum and toEnum, since many types that have reasonable implementations for succ and pred have more inhabitants than Int does.

10. type C_DBusSubtreeEnumerateFunc = Ptr DBusConnection -> CString -> CString -> Ptr () -> IO Ptr CString

    gi-gio	GI.Gio.Callbacks

    Type for the callback on the (unwrapped) C side.
