Struct Slab 

pub struct Slab<T> { /* private fields */ }

Implementations

impl<T> Slab<T>

pub fn new() -> Slab<T>

Creates a new Slab

pub fn with_capacity(capacity: usize) -> Slab<T>

Creates a new, empty Slab with room for capacity elems

Panics

• If the host system is out of memory

pub fn insert(&mut self, elem: T)

Inserts a new element into the slab, re-allocating if neccessary.

Panics

• If the host system is out of memory.

pub fn remove(&mut self, offset: usize) -> T

Removes the element at offset.

Panics

• If offset is out of bounds.

pub fn len(&self) -> usize

Returns the number of elements in the slab

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

Returns an iterator over the slab

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

Returns a mutable iterator over the slab

Trait Implementations

impl<T> Drop for Slab<T>

fn drop(&mut self)

Executes the destructor for this type.

impl<T> Index<usize> for Slab<T>

type Output = T

The returned type after indexing.

fn index(&self, index: usize) -> &Self::Output

Performs the indexing (container[index]) operation.

impl<'a, T> IntoIterator for &'a Slab<T>

type Item = &'a T

The type of the elements being iterated over.

type IntoIter = SlabIter<'a, T>

Which kind of iterator are we turning this into?
