The safety designed into Rust is suddenly foreign to the C family that I'm honestly not sure you can do that. Even "unsafe" Rust doesn't completely switch off the enforced safety

[โ€“] InnerScientist@lemmy.world 3 points 21 hours ago

Yeah, to quote the manual:

"[Unsafe Rust allows you to]

  • Dereference a raw pointer.
  • Call an unsafe function or method.
  • Access or modify a mutable static variable.
  • Implement an unsafe trait.
  • Access fields of unions.

[...] The unsafe keyword only gives you access to these five features that are then not checked by the compiler for memory safety."
