Here they write that
Literal types are the types of constexpr variables
However it seems to me that I can't define a constexpr string (it doesn't matter if it has static storage duration or is just a stack-allocated constexpr var).
But there are the requirements for literal types:
A literal type is any of the following:
- possibly cv-qualified class type that has all of the following properties:
- has a [trivial (until C++20) | constexpr (since C++20)] destructor,
- is one of
- a type with at least one constexpr (possibly template) constructor that is not a copy or move constructor,
Does std::string satisfy these requirements? Or does it maybe fast a non-conformant destructor?
There seems to be no link to the dtor here https://en.cppreference.com/w/cpp/string/basic_string.
I understand that it can't be made fully constexpr (at least for now) because of free store allocation.
I'm just asking whether it is a literal type.
