> Zig is definitely not as safe as either Rust or Fil-C, since Zig doesn't have a great story for use after free. Have you considered making... Fil-Zig? Would it be easier to do because Zig is already fairly far ahead of C in terms of safety? > Rust is less safe than Fil-C in practice, because Rust code uses `unsafe` a lot (>100 uses of `unsafe` in uutils and sudo-rs, for example), and Rust code ends up depending on an unsafe stack (like calling into libc, but also lots of other dependent libraries that are written in C). To be fair `sudo-rs`'s usage of unsafe is all there just to interface with C code (e.g. PAM) so it isn't really sudo-rs that is "less safe", it's just that PAM isn't any safer (because it's unmodified C). Also you can use Rust without libc - https://github.com/sunfishcode/mustang https://github.com/sunfishcode/mustang - unfortunately it doesn't seem to have gained much traction which I think is a shame because glibc is a curse. Most Rust programs actually have very few C dependencies. The big exceptions are libc and OpenSSL, but I think they'll be excised eventually.
