Sourceval map : ('b, 'cmp, ('a, _) t -> f:('a -> 'b) -> ('b, 'cmp) t) Base.Set.With_comparator.t

The types of map and filter_map are subtle. The input set, ('a, _) set, reflects the fact that these functions take a set of *any* type, with any comparator, while the output set, ('b, 'cmp) t, reflects that the output set has the particular 'cmp of the creation function. The comparator can come in one of three ways, depending on which set module is used

  • Set.map -- comparator comes as an argument
  • Set.Poly.map -- comparator is polymorphic comparison
  • Foo.Set.map -- comparator is Foo.comparator
Sourceval filter_map : ('b, 'cmp, ('a, _) t -> f:('a -> 'b option) -> ('b, 'cmp) t) Base.Set.With_comparator.t
Sourceval of_tree : ('a, 'cmp, ('a, 'cmp) Tree.t -> ('a, 'cmp) t) Base.Set.With_comparator.t
Sourceval of_hash_set : ('a, 'cmp, 'a Hash_set.t -> ('a, 'cmp) t) Base.Set.With_comparator.t
Sourceval of_hashtbl_keys : ('a, 'cmp, ('a, _) Hashtbl.t -> ('a, 'cmp) t) Base.Set.With_comparator.t
Sourceval of_map_keys : ('a, _, 'cmp) Base.Map.t -> ('a, 'cmp) t

Never requires a comparator because it can get one from the input Map.t.
