Integer overflows can be handled with the `checked_add` family of functions. Indexing can be handled with `get` and `get_mut` on slices. Some choose to develop Rust libraries/projects using only APIs that explicitly cannot panic. It's certainly not for everyone, but I find it incredible that Rust allows that option to develop code that is not only safe, but also robust against crashing the process (1). 1 - barring compiler/standard library bugs and OOM, which more so depends on the runtime
