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

If r represents a reference type T, returns a reflection that represents the type referred to by T with its topmost cv-qualifiers removed. Otherwise, returns r with its topmost cv-qualifiers removed.

Parameters

r

-

a reflection value

Return value

A reflection of the underlying type T, with reference (if present) and topmost cv-qualifiers removed.

Exceptions

Throws std::meta::exception if r does not represent a type or type alias.

Example

Run this code

#include <meta>

static_assert
(
    (remove_cvref(^^int) == ^^int) &&
    (remove_cvref(^^const int&) == ^^int) &&
    (remove_cvref(^^volatile int&&) == ^^int) &&
    (remove_cvref(^^const int&) == ^^int) &&
    (remove_cvref(^^const int[2]) == ^^int[2]) &&
    (remove_cvref(^^const int(&)[2]) == ^^int[2]) &&
    (remove_cvref(^^int(int)) == ^^int(int))
);

int main() {}
