Module vector 

Structs

Iter

Java Base.rangedIterator: walks the tree one 32-element chunk at a time instead of re-descending per element.

Mutable

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.
