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

Returns true if r represents a deleted function. Otherwise returns false.

Parameters

r

-

a reflection value

Return value

true if r represents a deleted function; otherwise false.

Example

Run this code

#include <meta>

struct Base
{
    bool operator==(const Base&) const = delete;
};

struct Derived : public Base
{
    bool operator==(const Derived&) const = default; // implicitly deleted
};

static_assert(std::meta::is_deleted(^^Base::operator==));
static_assert(std::meta::is_deleted(^^Derived::operator==));

int main() {}
