How would you describe the aliasing requirements of C and Rust, and do you consider them the same, as well as equally difficult?

- woodruffw 9mo agoSafe Rust has more strict aliasing requirements than C, so to write sound unsafe Rust that interoperates with safe Rust you need to do more work than the equivalent C code would involve. But per above, this is the apples-and-oranges comparison: the equivalent C code will compile, but is statistically more likely to be incorrect. Moreover, it's going to be incorrect in a way that isn't localizable.
