Detailed Description

The struct CountsSnapshot stores the count of each VarKind, and also of each constraint type.

getCounts() returns a CountsSnapshot object describing the current state of the IntegerRelation. truncate() truncates all vars of each VarKind and all constraints of both kinds beyond the counts in the specified CountsSnapshot object. This can be used to achieve rudimentary rollback support. As long as none of the existing constraints or vars are disturbed, and only additional vars or constraints are added, this addition can be rolled back using truncate.
