Mojo Safety Guarantees

I know mojo is trying to bring a lot of modern features to a "python superset". Rust has been talked about (include ownership/borrow) and rust is known for never crashing (excluding external factors). my question is, how much is the mojo compiler going to force/guarantee safety, or to what extent?

assuming i use, say fn instead of def?

Mojo has a Rust-style borrow checker (with similar rules) and Lifetimes. If you use fn and struct you're forced to make everything explicit which should give you as much safety as you have in Rust (assuming you don't use unsafe pointer). On the other hand, being a Python superset means Mojo gets to have all the dynamic parts of Python (in class and def) so you can write programs that'll crash at runtime due to type issues.
