Checks if (1-3) the underlying layout mapping map_ or (4-6) its type mapping_type models the semantics of LayoutMapping's predicate mapping traits.
1-3) Let
func be (1) is_unique, (2) is_exhaustive, or (3) is_strided, then it's equivalent to return map_.func();.4-6) Let
func be (4) is_always_unique, (5) is_always_exhaustive, or (6) is_always_strided, then it's equivalent to return mapping_type::func();.Parameters
(none)
Return value
See above.
