I think it was an index out of bounds type error. Can't quite remember.

To be clear, it was my inexperience with Rust, rather than a the language that was the problem. I found it amusing when I had read a few comments saying that "if it compiles it will run".

The person you were replying to said it will run without certain types of errors, not "it will run".

Yes, that would be a panic.
