How does rust handle this?

  I've never used rust, but from what I've heard, it crashes in debug mode, and wraps (two's complement) in release mode.

    That’s the default semantics, yes.

Shame the performance cost is too much to do same in release. Whenever wraparound semantics it is actually wanted, one can use an appropriate type.
