Detailed Description

Scope guard for code that allows arbitrary isl function to return an error if the max-operations quota exceeds.

This allows to opt-in code sections that have known long executions times. code not in a hot path can continue to assume that no unexpected error occurs.

This is typically used inside a nested IslMaxOperationsGuard scope. The IslMaxOperationsGuard defines the number of allowed base operations for some code, IslQuotaScope defines where it is allowed to return an error result.

Enter a quota-aware scope.

Should not be used directly. Use IslMaxOperationsGuard::enter() instead.
