Neither Rust nor Zig are appropriate at this time for certified functional safety. Given the definition of the languages is "it does what one particular implementation of its compiler, runtime, and standard library does at this time" it's not possible to construct a workable safety case for their use. Enthusiam and neat ideas are not sufficient to certify a development tool for functional safety.
