Unraveling string_view: Basics, Benefits, and Best Practices ## JASMINE LOPEZ & PRITHVI OKADE 20 24 September 15 - 20 ## Topics • Motivation • Performance benefits & basics • string_view: Constructors Constructors, useful functions • string vs. string_view and their 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. ## Motivation • Consider a function foo which operates on an immutable string. • In C++ we generally will create it with the following signature. 1 void foo(const std::string&

## +23 ## Optimizing Away Virtual Functions May Be Pointless ## SHACHAR SHEMESH Slide #2 - who am I?  ## DO NOT ENTER reviewer's notes: There are interesting technical details and surprising conclusions that virtual functions can be actually faster. Since CPU architectures are mentioned, I'd expect to see deep assembly vtable lookup. Does it even matter? ### WEKA DriveU.auto ## Conclusions - The notion that “virtual functions are slower” is flat out wrong. ○ Which is not to say they are faster o Some of the suggested alternatives
