Implementations

impl<T> StackRef<T>

where T: Stackable,

pub fn len(&self) -> usize

Returns the number of items in the stack.

pub fn iter(&self) -> Iter<'_, T>

pub fn iter_mut(&mut self) -> IterMut<'_, T>

pub fn get(&self, idx: usize) -> Option<&<T as ForeignType>::Ref>

Returns a reference to the element at the given index in the stack or None if the index is out of bounds

pub fn get_mut(&mut self, idx: usize) -> Option<&mut <T as ForeignType>::Ref>

Returns a mutable reference to the element at the given index in the stack or None if the index is out of bounds

pub fn push(&mut self, data: T) -> Result<(), ErrorStack>

Pushes a value onto the top of the stack.

pub fn pop(&mut self) -> Option<T>

Removes the last element from the stack and returns it.

Trait Implementations

impl<T> AsRef<StackRef<T>> for Stack<T>

where T: Stackable,

fn as_ref(&self) -> &StackRef<T>

Converts this type into a shared reference of the (usually inferred) input type.

impl<T> Borrow<StackRef<T>> for Stack<T>

where T: Stackable,

fn borrow(&self) -> &StackRef<T>
