Ord a => Monoid (NubList a) Source #	Monoid operations on NubLists. For a valid Monoid instance we need to satistfy the required monoid laws; identity, associativity and closure. Identity : by inspection: mempty `mappend` NubList xs == NubList xs `mappend` mempty Associativity : by inspection: (NubList xs `mappend` NubList ys) `mappend` NubList zs == NubList xs `mappend` (NubList ys `mappend` NubList zs) Closure : appending two lists of type a and removing duplicates obviously does not change the type.

(Ord a, Binary a) => Binary (NubList a) Source #	Binary instance for 'NubList a' is the same as for '[a]'. For `put`, we just pull off constructor and put the list. For `get`, we get the list and make a `NubList` out of it using `toNubList`.

toNubList :: Ord a => [a] -> NubList a Source #

Smart constructor for the NubList type.

fromNubList :: NubList a -> [a] Source #

overNubList :: Ord a => ([a] -> [a]) -> NubList a -> NubList a Source #

Lift a function over lists to a function over NubLists.

data NubListR a Source #

NubListR : A right-biased version of NubList. That is toNubListR ["-XNoFoo", "-XFoo", "-XNoFoo"] will result in ["-XFoo", "-XNoFoo"], unlike the normal NubList, which is left-biased. Built on top of ordNubRight and listUnionRight.
