If
T
is a valid type for the second argument to
copy_from
,
copy_to
or the corresponding load constructors of
simd
or
simd_mask
, provides the member constant
value
equal
true
. For any other type,
value
is
false
.

Example
Run this code
#include <experimental/simd> #include <iostream> int main() { namespace stdx = std::experimental; std::cout << std::boolalpha << stdx::is_simd_flag_type_v<stdx::element_aligned_tag> << '\n' << stdx::is_simd_flag_type_v<int> << '\n'; }
Output:
true false
