Struct rpds::stack::Stack

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

A persistent stack with structural sharing.

Complexity

Let n be the number of elements in the stack.

Temporal complexity

Operation	Average	Worst case
new()	Θ(1)	Θ(1)
push()	Θ(1)	Θ(1)
pop()	Θ(1)	Θ(1)
peek()	Θ(1)	Θ(1)
size()	Θ(1)	Θ(1)
clone()	Θ(1)	Θ(1)
iterator creation	Θ(1)	Θ(1)
iterator step	Θ(1)	Θ(1)
iterator full	Θ(n)	Θ(n)

Implementation details

This is a thin wrapper around a List.

impl<T: Ord, P> Ord for Stack<T, P>

where P: SharedPointerKind,

fn cmp(&self, other: &Stack<T, P>) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.
