Module Core_set_intf

module Core_set_intf: sig .. end

This module defines interfaces used in Core.Std.Set. This module uses the same organizational approach as Core_map_intf. See the documentation in core_map.mli for a description of the approach.

This module defines module types {Creators,Accessors}{0,1,2,_generic,_with_comparator}. It uses check functors to ensure that each module types is an instance of the corresponding _generic one.

This module defines interfaces used in Core.Std.Set. This module uses the same organizational approach as Core_map_intf. See the documentation in core_map.mli for a description of the approach.

This module defines module types {Creators,Accessors}{0,1,2,_generic,_with_comparator}. It uses check functors to ensure that each module types is an instance of the corresponding _generic one.

We must treat Creators and Accessors separately, because we sometimes need to choose different instantiations of their options. In particular, Set itself matches Creators2_with_comparator but Accessors2 (without comparator).

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
