Defined in header <meta>
consteval bool is_mutable_member( std::meta::info r );		(since C++26)

Returns true if r represents a mutable non-static data member. Otherwise returns false.

Parameters

r

-

a reflection value

Return value

true if r represents a mutable non-static data member; otherwise false.

Example

Run this code

#include <meta>

struct A
{
    static int a;
    mutable int b;
};

static_assert(!std::meta::is_mutable_member(^^A::a));
static_assert(std::meta::is_mutable_member(^^A::b));

int main() {}
