insertBy :: Compare a -> a -> OrdSeq a -> OrdSeq a Source #
Insert into a monotone OrdSeq.

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
