`std::string_view` is essentially something like this: struct string_view { char *data; size_t length; } It is a pointer to a subset of an existing string. It has all of the existing features of `std::string` but passing it around is zero copy. As long as the original memory allocation exists your `string_view`s are still valid. Also, it has an implicit constructor from `const std::string` and `const char #` allowing you you define a single function like `Thing ParseThing(std::string_view line)` and accept `char #` and `std::string` as an input.
