A Deep Dive into string_view
string_view is a type introduced in C++17 that appears simple but holds hidden complexities. It is merely a pointer paired with a length, yet it can replace numerous const std::string& parameters and eliminate unnecessary string allocations. However, misuse can introduce fatal issues like dangling references and missing null terminators. In this chapter, we cover every aspect of string_view from underlying principles to performance and common pitfalls.
