Struct Mutable 

pub struct Mutable<E> { /* private fields */ }

Transient vector. Unlike Java’s 32-slot scratch tail with null padding, the Rust tail is a Vec<E> whose length is always exactly size - tailoff(size); the “scratch” behaviour comes from in-place push/pop on that Vec. All tree nodes touched by the transient are stamped with its token and mutated in place only while uniquely owned (Rc::strong_count == 1), matching Java’s edit-token discipline.
