(** CMRAs for sets with union and disjoint union. *)
(** To define these CMRAs generically without breaking canonical
structures, we bundle the (mainly) typeclass instances used by the
CMRAs into canonical structures. These TC instances are defined
elsewhere, so we keep our `typeclass_instances` hints `Local`.
structures, we bundle the assumptions made by the CMRAs into canonical
structures. These assumptions are mainly typeclass instances. These TC
instances are defined elsewhere, so we keep our `typeclass_instances`
hints `Local`.
To use these CMRAs with a set implementation, define canonical
structures for
- [semi_setT] the union CMRA (suffix "U")
- [semi_setT] assumptions made by the union CMRA (suffix "U")
- [disjoint_setT] the disjoint union CMRA (suffix "D")
- [disjoint_setT] assumptions made by the disjoint union CMRA (suffix
"D")
- [fresh_setT] a "subclass" of [disjoint_setT] with extra assumptions
enabling local updates (in the disjoint union CMRA) for allocating
enabling, in the disjoint union CMRA, local updates for allocating
elements not in a finite set (suffix "DF")
The `std++` type [gset], for example, supports all three via [gsetU],
