pub struct StackRef<T: Stackable>(/* private fields */);

Implementations

impl<T: Stackable> StackRef<T>

pub fn len(&self) -> usize

Returns the number of items in the stack.

pub fn is_empty(&self) -> bool

Determines if the stack is empty.

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

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

pub fn get(&self, idx: usize) -> Option<&T::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::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: Stackable> AsRef<StackRef<T>> for Stack<T>

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

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

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

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

Immutably borrows from an owned value.

impl<T: Stackable> ForeignTypeRef for StackRef<T>

type CType = <T as Stackable>::StackType

The raw C type.

unsafe fn from_ptr<'a>(ptr: *mut Self::CType) -> &'a Self

Constructs a shared instance of this type from its raw type.

unsafe fn from_ptr_mut<'a>(ptr: *mut Self::CType) -> &'a mut Self

Constructs a mutable reference of this type from its raw type.

fn as_ptr(&self) -> *mut Self::CType

Returns a raw pointer to the wrapped value.

impl<T: Stackable> Index<usize> for StackRef<T>

type Output = <T as ForeignType>::Ref

The returned type after indexing.

fn index(&self, index: usize) -> &T::Ref

Performs the indexing (container[index]) operation.

impl<T: Stackable> IndexMut<usize> for StackRef<T>

fn index_mut(&mut self, index: usize) -> &mut T::Ref

Performs the mutable indexing (container[index]) operation.

impl<'a, T: Stackable> IntoIterator for &'a StackRef<T>

type Item = &'a <T as ForeignType>::Ref

The type of the elements being iterated over.

type IntoIter = Iter<'a, T>

Which kind of iterator are we turning this into?

fn into_iter(self) -> Iter<'a, T>

Creates an iterator from a value.

impl<'a, T: Stackable> IntoIterator for &'a mut StackRef<T>

type Item = &'a mut <T as ForeignType>::Ref

The type of the elements being iterated over.

type IntoIter = IterMut<'a, T>

Which kind of iterator are we turning this into?

fn into_iter(self) -> IterMut<'a, T>

Creates an iterator from a value.

impl<T: Stackable + Send> Send for StackRef<T>

impl<T: Stackable + Sync> Sync for StackRef<T>

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
