> code that follows Rust's tree-style ownership pattern This is a pretty important qualification. Most low-level systems code doesn't and can't have this ownership structure. It provides a reason why Rust has more traction replacing code that could have been written in Java rather than e.g. C++ in the domains where C++ excels (like database engines).
