Correct by Construction: APIs That Are Easy to Use and Hard to Misuse

Matt Godbolt

60 minute presentation

C++ gives us an awful lot of powerful constructs to use when designing APIs: strong types, RAII, templates, virtual functions and more. Some are easier to use than others, and some might be easy to use but easy to misuse. In this talk, Matt will cover some of the techniques you can use in your API and code in general to make it more difficult for users to make mistakes. You'll leave the talk with some new ideas to try out in your code bases: your future users (maybe yourself the very next day...) will thank you!
