Can a zero-terminated string view return the size?
The "zero-terminated string view", much like std::string_view, holds a pointer and a size, so it can return the size in constant time. (It also has to maintain an invariant that the null-terminator mark is consistent with the separately stored size.) Regards, &rzej;

Hi Everyone, Would Boost libraries benefit from having a string_view-like type with the guarantee that the underlying character sequence is null-terminated?
This could be as yet another Boost library, or as part of Boost.Core. Maybe Boost already has such a type somewhere?
The need for such a type surfaces time and again. When a library needs to be passed both const char * and std::string cheaply, only to pass it down to low-level C-libraries later. We have seen one recently during the review of Boost.Sqlite. One is again proposed for standardization: wg21.link/p3655.
