Why do you say Rust is easier to start with than C or C++?
[Disclaimer : i'm old enough to dream in K&R C and later ANSI C, and then C++, but am more than enthused about Rust, so a genuine question]

C is so small a language that you can learn it much quicker. The problems surface later on.
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!

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.
I think it's hard for those who carry "mindset-baggage" from C/C++. My first attempt at Rust was a failure mostly because I thought it was sort of a "weird C/C++".
In fact if I could, I would like that writing in C was prohibited by law to permit holders only, the jury being rob pike and richard stallman themselves!
emscripten is no longer required for Rust to target WASM. There is a new target of wasm32-unknown-unknown. This project gives you quick bootstrap instructions into WASM with Rust:

Very quick to get started with, and the examples get you going quickly. I just used it yesterday (nothing fancy), and everything worked right out of the box.
