type Compare a = a -> a -> Ordering Source #

insertBy :: Compare a -> a -> OrdSeq a -> OrdSeq a Source #

Insert into a monotone OrdSeq.

pre: the comparator maintains monotonicity

\(O(\log^2 n)\)

insert :: Ord a => a -> OrdSeq a -> OrdSeq a Source #

Insert into a sorted OrdSeq

\(O(\log^2 n)\)

splitOn :: Ord b => (a -> b) -> b -> OrdSeq a -> (OrdSeq a, OrdSeq a, OrdSeq a) Source #

Given a monotonic function f that maps a to b, split the sequence s depending on the b values. I.e. the result (l,m,r) is such that * all (< x) . fmap f $ l * all (== x) . fmap f $ m * all (> x) . fmap f $ r

>>> splitOn id 3 $ fromAscList' [1..5]

Given a monotonic predicate p, splits the sequence s into two sequences (as,bs) such that all (not p) as and all p bs
