related: async/await is also amazingly useful for game development. Stuff like writing an update loop, where `yield` is "wait until next frame to continue".
This can let you avoid a lot of the pomp and circumstance of writing state machines by hand.
Thanks. I was a software engineer at several different SF-area companies for about a decade, and then I decided to take some time off from professional programming. I'm now a full-time student in a CS Master's program. As I'll eventually need to produce a thesis, this was partly an exercise to practice my technical writing.
I picked up Rust for my personal projects a couple of years ago, and mostly worked from the official API docs, occasionally turning to blog posts, the Rust book, or the Rustonomicon. Because I didn't have any time pressure, I ignored the entire crate ecosystem and opted to write everything myself instead. This has left some giant gaps in my Rust knowledge, but they're in a different place than is typical.
As far as the explanations go, I realized that good authors don't say important things only once: they repeat everything a few different times in a few different ways. So, I tried to say the exact same things in the prose as in the code listings, and trusted that the fundamental differences between Rust and English would make the two complement each other instead of simply being repetitive.
