Trait Implementations

impl<T> UnprotectedStorage<T> for HashMapStorage<T>

fn new() -> Self

Creates a new Storage<T>. This is called when you register a new component type within the world.

unsafe fn clean<F>(&mut self, _: F) where F: Fn(Index) -> bool

Clean the storage given a check to figure out if an index is valid or not. Allows us to safely drop the storage.

unsafe fn get(&self, id: Index) -> &T

Tries reading the data associated with an Index. This is unsafe because the external set used to protect this storage is absent.

unsafe fn get_mut(&mut self, id: Index) -> &mut T

Tries mutating the data associated with an Index. This is unsafe because the external set used to protect this storage is absent.

unsafe fn insert(&mut self, id: Index, v: T)

Inserts new data for a given Index.

unsafe fn remove(&mut self, id: Index) -> T
