Checks if (1-3) the underlying layout mapping map_
or (4-6) its type mapping_type
models the semantics of LayoutMapping
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.
