stdremovecv

stdremovecv is an informal shorthand for the C++ standard type trait std::remove_cv. The official name and usage come from the standard library header <type_traits>. The trait yields a version of a type with its top-level const and volatile qualifiers removed.

The remove_cv trait is defined as a class template with a member type named type. Its primary form yields the type unchanged, while specializations strip the cv-qualifiers. In practice, the trait can also be accessed via the alias template remove_cv_t<T>, introduced in C++14, which provides a concise way to refer to the resulting type without writing ::type.

For example, remove_cv_t<int const> is int, and remove_cv_t<int const volatile> is int. When T is a pointer type such as int const*, remove_cv_t<int const*> remains int const* because the top-level qualifiers do not apply to the pointed-to type; remove_cv only affects top-level cv-qualifiers of T itself.

Common use cases include generic programming where a type must be treated uniformly regardless of cv-qualifiers, such as when implementing other type traits, type normalization, or template metaprogramming that depends on an underlying non- cv-qualified type. It is frequently combined with other traits, such as std::remove_const, std::remove_volatile, or std::remove_reference, to form more complex type transformations.

Notes: std::remove_cv and its alias are part of the C++ standard library and reside in <type_traits>. Other related traits include std::remove_const, std::remove_volatile, and in C++20, std::remove_cvref, which additionally removes references. The term stdremovecv is not a standard name but is commonly used informally to refer to std::remove_cv.
