demonstrated on day 3). • At runtime, a &dyn Pet is represented as a ”fat pointer”, i.e. a pair of two pointers: One pointer points to the concrete object that implements Pet, and the other points to the vtable (e.g. for add_3) and Clone (e.g. multiply_sum), depending on what the closure captures. Function pointers (references to fn items) implement Copy and Fn. 103 By default, closures will capture each variable objects can be used with references, e.g &dyn Pet. However, we can also use trait objects with smart pointers like Box to create an owned trait object: Box. struct Dog { name: String, age: i8, }

are fully contained inside a single curve option. They are created internally and none of their pointers are ever exposed to the outer world. Official documentation Lager Source code: https://github various platforms, but of course Linux is easiest. Working with the Krita codebase Here's some pointers for working with our codebase. Architecture The code base changes all the time with Krita, we're The most important step to learning the code is to really understand memory management: pointers, smart pointers and pointer arithmetic. This is something that Java and C# developers will need to spend
