Probably just need to make safe bindings for this simple function and add to the public API. It's useful for app debugging.

This is a test of what is possible with alloc feature enabled. In reality, the From trait implementation should use the TryFrom trait implementation and just call .unwrap() here. People will decide which guarantees they want to have.
