pub struct MemoryStorage<T, U>
where
    U: AsRef<[Slot<T>]> + AsMut<[Slot<T>]>,
{ /* private fields */ }

The instance that will store all the items.

Implementations

impl<T> MemoryStorage<T, SlotVec<T>>

pub fn push(&mut self, item: T) -> Id

Push an item ignoring capacity limits. Once the max capacity has been reached the vec simply allocates more space.

impl<T, U> MemoryStorage<T, U>

where U: AsRef<[Slot<T>]> + AsMut<[Slot<T>]>,

pub fn clear(&mut self)

Clears the storage by turning taken slots into free slots.

pub fn insert(&mut self, item: T) -> Result<Id, InternalStorageFullError<T>>

Try to insert an item. Returning the ID on a successful insert and returning the item wrapped in an error whenever there’s no space left.

pub fn remove(&mut self, id: Id) -> T

Removes an item without shifting the items after it to the left and without invalidating their IDs.

pub fn get(&self, id: Id) -> Option<&T>

Returns a reference to an item whenever it is present.

pub fn get_mut(&mut self, id: Id) -> Option<&mut T>

Returns a mutable reference to an item whenever it is present.

pub fn capacity(&self) -> usize

Returns the current capacity.

pub fn taken_slots(&self) -> usize

Returns how many slots are currently in use.

pub fn storage_ref(&self) -> &U

Acquire a reference to the storage.

pub fn storage(self) -> U

Destroy the instance and acquire the storage.
