Course feedback: more Chapter 4

[wangpatrick57]

I read through all of Chapter 4 in Brown's version of RPL and did all the exercises. I found that it was the most important chapter to understanding everything else about Rust. I don't think it'd be too much to spend a full 5-10 weeks just on Chapter 4 (+ lifetimes, since they're related) to really go through it in-depth.

When I read Brown RPL, I tried to "predict" the diagrams they would draw for each code snippet. I think this would be a great homework in addition to their "official" exercises.
