std::meta::is_data_member_spec

constexpr std::meta::info is_data_member_spec( std::meta::info r );

Determines if r represents a data member description (returned by std::meta::data_member_spec). Returns true if it does, false otherwise.

Parameters

Return value

true if r represents a data member description, false otherwise.

Notes

Data member descriptions can be reified to data members of a class using std::meta::define_aggregate.

Example

#include <meta>

static_assert(!std::meta::is_data_member_spec(^^int)); // ^^int is not a data member spec

constexpr auto spec = std::meta::data_member_spec(^^int, {.name = "x"});
static_assert(std::meta::is_data_member_spec(spec)); // spec is a data member spec

int main() {}
