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

Returns true if r represents an alias template. Otherwise returns false.

Parameters

r

-

a reflection value

Return value

true if r represents an alias template; otherwise false.

Example

Run this code

#include <list>
#include <meta>

// type alias
using Int = int;
static_assert(!std::meta::is_alias_template(^^Int));

// type alias template
template<typename T>
using List = std::list<T>;
static_assert(std::meta::is_alias_template(^^List));

int main() {}
