Struct RedBlackTreeSet 

pub struct RedBlackTreeSet<T, P = RcK>
where
    T: Ord,
    P: SharedPointerKind,
{ /* private fields */ }

A persistent set with structural sharing. This implementation uses a red-black tree.

Complexity

Let n be the number of elements in the set.

Temporal complexity

Operation	Average	Worst case
new()	Θ(1)	Θ(1)
insert()	Θ(log(n))	Θ(log(n))
remove()	Θ(log(n))	Θ(log(n))
get()	Θ(log(n))	Θ(log(n))
contains()	Θ(log(n))	Θ(log(n))
size()	Θ(1)	Θ(1)
clone()	Θ(1)	Θ(1)
iterator creation	Θ(log(n))	Θ(log(n))
iterator step	Θ(1)	Θ(log(n))
iterator full	Θ(n)	Θ(n)

Implementation details

This is a thin wrapper around a RedBlackTreeMap.
