Under the hood it's just "std::pair<const char, std::size_t>". It's like an abstract data type or a newtype in Haskell: construction of the aliased type is restricted to the functions that are provided. You are correct, there is no safety --- you can call the constructor std::string_view(const char, size_t) and stuff anything you want in there. The main reason string_view is nice is the implicit conversions you get from the other string types. Pass in a "const char*", it finds the terminating null for you. Pass in a std::string, no problem. No boilerplate. |
