Static Public Attributes
static constexpr auto	base = Base
	The value of the policy's FilterBase.

template<class... TargetIncludes>
static constexpr bool	HasAccess = (FilterType::template included<TargetIncludes> && ...)
	Indicates whether all requested types are accessible by the policy.

template<FilterBase TargetBase>
static constexpr bool	BaseContains = Base >= TargetBase
	Indicates the policy's FilterBase is at least as permissive as the requested base.

template<FilterBase TargetBase, class... TargetIncludes>
static constexpr bool	ConvertibleTo = BaseContains<TargetBase> && HasAccess<TargetIncludes...>
	Indicates whether the policy is convertible to another policy with the requested ruleset.

Detailed Description

template<FilterBase Base, class... Includes>
