You’ll probably be waiting a long time, since Rust very explicitly doesn’t have “leak safety” as a constructive property. Safe Rust programs are allowed to leak memory, because memory leaks themselves don’t cause safety issues.
There’s even a standard, non-unsafe API for leaking memory[1].
(What Rust does do is make it harder to construct programs that leak memory unintentionally. It’s possible but not guaranteed that a similar leak would be difficult to express idiomatically in Rust.)
