If you can make safe Rust segfault you're doing something wrong.
It actually is possible to segfault in safe Rust, although it is considered a bug. Proofs of concept are shown in this cve-rs crate.
If you want an explanation of why this happens, I recommend this video: https://youtu.be/vfMpIsJwpjU
IME Rust programs crash at about the same rate as other languages. "Rewrite everything in Rust" hasn't made much of a difference for me, so far.
A crash is different to a SEGFAULT. I'd be very surprised to see a safe rust program segfault unless it was actively exploiting a compiler bug.
