The standard library Disjoint_Sets_With_Constant_Time_Union api defines access to a standard datastructure useful for partitioning sets.
The Disjoint_Sets_With_Constant_Time_Union api is implemented by the disjoint_sets_with_constant_time_union package.
The Disjoint_Sets_With_Constant_Time_Union api source code is in src/lib/src/disjoint-sets-with-constant-time-union.api. The above information is manually maintained and may contain errors.
