Rust makes quite a few things more rigorous (e.g. pairing allocations with deallocations and reference validity). It basically fulfills the job of a static analyzer baked into the language.
It's also a vastly more analyzable language (in that its syntax is reasonably unambiguous and there's no dynamic runtime in play) and it can be integrated well.
Toolchain quality (error reporting, built in testing, awareness of primitives like "libraries", etc.) is also a huge strong point.
We're reasonably confident that we can use safe Rust as is, with strong guidance on how to do unsafe Rust.
For a tangible investigation of that space, PolySync has a project that has a look at MISRA rules from a Rust perspective. https://github.com/PolySync/misra-rust/blob/master/MISRA-Rul...
Ada is a good example here: the language has not evolved something like MISRA-C (it has evolved SPARK for formal verification, but I see that differently).
