I agree that in a thread about Rust systems programming, asking how Rust (and, come to think of it, Haskell) can do dynamic allocation on the bare metal is a good question. I think the good underlying question was devalued by what I think was the poster's lack of reflection. Obviously Rust can do it because Rust is magical, but Haskell? How would that ever work? Your interpretation may vary.
