A Deep Dive into string_view

string_view is a type introduced in C++17 that appears simple but hides considerable complexity. It consists of merely a pointer and a length, yet it can replace countless const std::string& parameters and eliminate unnecessary string allocations. However, if used incorrectly, it can introduce fatal issues like dangling references and missing null terminators. In this chapter, we cover everything about string_view from underlying principles to performance characteristics and common pitfalls.
