For the 5th time, I will be starting the Ray Tracing in One Weekend book in Rust
The biggest problem I encountered was with memory management: in particular with Rust's borrow checker. I totally ignored the concept of moved values, and thus, I needed to redo entire chapters because of my ignorance. I am beginning to understand the power of Rust's memory management model, but I still lack the fundementals; I got lots of reading to do.
I also encountered problems with porting C++ abstract classes and shared pointers to Rust. I used reference-counters (Rc) for multiple ownership, but I don't think I fully grasped what exactly I was doing. This shines through quite obviously with my inconsistent use of Rc and references. Plainly, I need to read more about memory management and references. Additionally, I used enums in place of abstract classes to group together similar structs which seemed like the best option at the time.
I learned a lot and got the ray tracer to work (a rust tracer if you will), so this would be one of my more successful projects to date.
