Unless what you are doing is not fit for what guarantees Rust gives you, the compiler should just be a crutch in case you missed a step.
It's hard to escape the mindset of languages we're used to!
> At the same time a lot of the error messages are very cryptic
You should file bugs! We care deeply about the legibility of error messages, and the whole --explain system is there to try and go above and beyond.
Next time I do some Rust I will. I also need to check out that --explain system. I didn't see that when learning Rust.
> error[E0384]: cannot assign twice to immutable variable `x`
That E0384 is a link in the browser. Click it and you go to https://doc.rust-lang.org/error-index.html#E0384 which has a longer version of this error.
On the command line, you can run `rustc --explain E0384` and it'll print out the same text to the terminal.
