Documentation

data NubList a Source #

NubList : A de-duplicated list that maintains the original order.

Structured a => Structured (NubList a) Source #

Methods

structure :: Proxy (NubList a) -> Structure Source #

structureHash' :: Tagged (NubList a) MD5

(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.

Methods

put :: NubList a -> Put #

get :: Get (NubList a) #

putList :: [NubList a] -> Put #

Ord a => Monoid (NubList a) Source #

Monoid operations on NubLists. For a valid Monoid instance we need to satisfy 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.

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.
