.get() will bounds check and the compiler will optimize that away if it can prove safety at compile time. That leaves you 3 options made available in Rust:

- Explicitly unsafe

- Runtime crash

- Runtime crash w/ compile time avoidence when possible

Catch the panic & unwind, safe program execution continues. Fundamentally impossible in Fil-C.
