C++: string_view: Deep dive Jasmine Lopez Prithvi Okade 1Topics • Motivation • Performance benefits & basics • string_view: Constructors, useful functions • string vs. string_view and their interoperability interoperability • When to use string_view • Using string_view safely • Intro to span • span vs. string_view • Case study of an optimization using string_view. 2Motivation • Consider a function foo will end up calling “2”. And the code will miss the niceties of using the string API set. string_view helps in resolving this problem elegantly.Motivation 4 void foo(const std::string& str); void foo(const
