My usual way(s) of learning a new language is, depending on whether I like it or not, to start following related content (eg. the Rust subreddit, read articles that are too long https://fasterthanli.me/ https://fasterthanli.me/ and https://matklad.github.io/ https://matklad.github.io/ , and watch hours of https://www.youtube.com/c/JonGjengset https://www.youtube.com/c/JonGjengset etc), then eventually attempt writing something in it. And based on all this copying a megabyte might be perfectly A-OK. Computers are fast, life is short, keep structs simple because they can get problematic (https://matklad.github.io/2020/12/28/csdi.html https://matklad.github.io/2020/12/28/csdi.html).
