Exact lookup

1. lookupGE :: Ord a => a -> NESet a -> Maybe a

   nonempty-containers	Data.Set.NonEmpty

   O(log n). Find smallest element greater or equal to the given one.

   lookupLT 3 (fromList (3 :| [5])) == Just 3
   lookupLT 4 (fromList (3 :| [5])) == Just 5
   lookupLT 6 (fromList (3 :| [5])) == Nothing
   

2. lookupGT :: Ord a => a -> NESet a -> Maybe a

   nonempty-containers	Data.Set.NonEmpty

   O(log n). Find smallest element greater than the given one.

   lookupLT 4 (fromList (3 :| [5])) == Just 5
   lookupLT 5 (fromList (3 :| [5])) == Nothing
   

3. lookupIndex :: Ord a => a -> NESet a -> Maybe Int

   nonempty-containers	Data.Set.NonEmpty

   O(log n). Lookup the index of an element, which is its zero-based index in the sorted sequence of elements. The index is a number from 0 up to, but not including, the size of the set.

   isJust   (lookupIndex 2 (fromList (5:|[3]))) == False
   fromJust (lookupIndex 3 (fromList (5:|[3]))) == 0
   fromJust (lookupIndex 5 (fromList (5:|[3]))) == 1
   isJust   (lookupIndex 6 (fromList (5:|[3]))) == False
   

4. lookupLE :: Ord a => a -> NESet a -> Maybe a

   nonempty-containers	Data.Set.NonEmpty

   O(log n). Find largest element smaller or equal to the given one.

   lookupLT 2 (fromList (3 :| [5])) == Nothing
   lookupLT 4 (fromList (3 :| [5])) == Just 3
   lookupLT 5 (fromList (3 :| [5])) == Just 5
   

5. lookupLT :: Ord a => a -> NESet a -> Maybe a

   nonempty-containers	Data.Set.NonEmpty

   O(log n). Find largest element smaller than the given one.

   lookupLT 3 (fromList (3 :| [5])) == Nothing
   lookupLT 5 (fromList (3 :| [5])) == Just 3
   

6. lookupSyntax :: Text -> SyntaxMap -> Maybe Syntax

   skylighting	Skylighting

   Lookup syntax by (in order) full name (case insensitive), short name (case insensitive), extension.

7. lookupLang :: Lang -> [(Lang, a)] -> Maybe (Lang, a)

   unicode-collation	Text.Collate.Lang

   Find best match for a Lang in an association list.

8. lookupEQ :: Int -> PrimeIntSet -> Maybe (Prime Int)

   arithmoi	Math.NumberTheory.Primes.IntSet

   Find a prime in the set, equal to the given integer, if any exists.

9. lookupGE :: Int -> PrimeIntSet -> Maybe (Prime Int)

   arithmoi	Math.NumberTheory.Primes.IntSet

   Find the smallest prime in the set, greater or equal to the given integer, if any exists.

10. lookupGT :: Int -> PrimeIntSet -> Maybe (Prime Int)

    arithmoi	Math.NumberTheory.Primes.IntSet

    Find the smallest prime in the set, greater than the given integer, if any exists.
