I could give you a crash course from the perspective of X whatever language you know over IRC or Discord or so if you want, work looks like it will be slow today (considering over half the people are gone, lol).
But from my personal perspective, the reason why Rust might have a higher learning curve is not because its harder to learn (honestly I think it’s much easier to learn than ‘most’ languages), it just doesn’t let you write bad code, so what most languages would have accepted but would have just been outright wrong, Rust will not accept, it forces you to write good code, and that’s a skill you can take back to any other language.
EDIT: Remember the first line in the article after all, there’s a reason for this!
Rust is a fast, reliable, and memory-efficient programming language. It’s been voted the most loved programming language six years in a row (survey).
6 years! And Rust doesn’t even have a huge SO presence because they have such a large community already on their own forums, their discord server, their zulip server, and reddit, which makes it even more astounding.
