Fields

okind :: Id a -> a

the content element at given id

ouniqGroup :: GroupName -> Id a

the id of the unique member of a singleton content group

opick :: GroupName -> (a -> Bool) -> Rnd (Maybe (Id a))

pick a random id belonging to a group and satisfying a predicate

ofoldrWithKey :: forall b. (Id a -> a -> b -> b) -> b -> b

fold over all content elements of a

ofoldrGroup :: forall b. GroupName -> (Int -> Id a -> a -> b -> b) -> b -> b

fold over the given group only

obounds :: !(Id a, Id a)

bounds of identifiers of content a

ospeedup :: !(Maybe (Speedup a))
