Rust for C++ programmers – part 4: unique pointers

In the same way that GC is, yes. Technically both are probably fully deterministic, just not readily determinable by casual examination of the code at compile time.

I guess I didn't mean nondeterministic in the philosophical indeterminism sense, but in the sense that different runs might produce different behavior.

Well, you can get there if you lag enough to drop a few frames in a competitive FPS game: while the game is still deterministic, the game/players system will diverge: a few dropped frames can get you fragged.

Also, some naive simulations will adapt the length of their steps with the time it takes to compute them. Any performance variation gives you full blown unpredictability.
