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

Returns true if r represents an operator function template. Otherwise returns false.

Parameters

r

-

a reflection value

Return value

true if r represents an operator function template; otherwise false.

Example

Run this code

#include <meta>

struct S
{
    // conversion function
    operator int();

    // conversion function template
    template<typename T>
    operator float();

    // operator function
    int operator[](int);

    // operator function template
    template<typename T>
    int operator+=(const S&);
};
static_assert(!is_operator_function_template(^^S::operator int));
static_assert(!is_operator_function_template(^^S::operator float));
static_assert(!is_operator_function_template(^^S::operator[]));
static_assert( is_operator_function_template(^^S::operator+=));

bool operator+ (S, S);
static_assert(!is_operator_function_template(^^operator+));

template <typename T>
bool operator- (S, S);
static_assert(is_operator_function_template(^^operator-));

int main() {}
