A backend allocator for TimerDriverBase.

Required Methods

fn insert(&mut self, value: T) -> u32

Panics

Panics if the key is not found

fn remove(&mut self, key: u32) -> T

Panics

Panics if the key is not found

fn get(&self, key: u32) -> Option<&T>

Get reference to the value by key.

fn get_mut(&mut self, key: u32) -> Option<&mut T>

Get mutable reference to the value by key.

fn clear(&mut self)

Clear all elements.

fn len(&self) -> usize

Get the number of elements.

Provided Methods

fn reserve(&mut self, additional: usize)

Reserve extra space than len() for slab.

For unsupported slab implementations(e.g. for embedded slabs), this method just does nothing.

fn is_empty(&self) -> bool

Check if slab allocator is empty
