View all issues with WP status.
std::vector's iterator and const_iterator are required to meet constexpr iterator requirements in C++20 per P1004R2, but it seems that the similar wording is missing for std::basic_string in both P0980R1 and the current working draft.I think we should add a bullet "The types iterator and const_iterator meet the constexpr iterator requirements (25.3.1 [iterator.requirements.general])." to 22.214.171.124 [basic.string.general].
[2022-01-30; Reflector poll]
Set status to Tentatively Ready after six votes in favour during reflector poll.
[2022-02-10 Approved at February 2022 virtual plenary. Status changed: Tentatively Ready → WP.]
This wording is relative to N4901.
Modify 126.96.36.199 [basic.string.general], as indicated:
-3- In all cases, [data(), data() + size()] is a valid range, data() + size() points at an object with value charT() (a "null terminator"), and size() <= capacity() is true.-4- A size_type parameter type in a basic_string deduction guide refers to the size_type member type of the type deduced by the deduction guide.
