The Stackable

required by the interpreter.
Associated Types
type Item
The kind of item the stack holds.
Required methods
fn is_empty(&self) -> bool
Checks whether the stack is empty.
fn as_slice(&self) -> &[Self::Item]
Extracts a slice containing the entire stack.
fn push(&mut self, item: Self::Item)
Appends one item to the end of the stack.
fn pop1(&mut self) -> Option<Self::Item>
Removes the last item of the stack and returns it, None
if
the stack is empty.
fn pop(&mut self, n: usize) -> Option<Vec<Self::Item>>
Removes n
elements from the end of the stack, None
if the
stack doesn't contain enough elements.
Returned items are in reverse order: the last element comes
last in the list.
fn peek1(&self) -> Option<&Self::Item>
Peek the last item of the stack and returns a reference to it,
