Struct rpds::stack::Stack
[−]
[src]
pub struct Stack<T> { /* fields omitted */ }
A persistent stack with structural sharing.
Complexity
Let n be the number of elements in the stack.
Temporal complexity
Operation | Best case | Average | Worst case |
---|---|---|---|
new() | Θ(1) | Θ(1) | Θ(1) |
push() | Θ(1) | Θ(1) | Θ(1) |
pop() | Θ(1) | Θ(1) | Θ(1) |
peek() | Θ(1) | Θ(1) | Θ(1) |
size() | Θ(1) | Θ(1) | Θ(1) |
clone() | Θ(1) | Θ(1) | Θ(1) |
iterator creation | Θ(1) | Θ(1) | Θ(1) |
iterator step | Θ(1) | Θ(1) | Θ(1) |
iterator full | Θ(n) | Θ(n) | Θ(n) |
Implementation details
This is a thin wrapper around a List
.
