pub struct Cache<A> { /* private fields */ }

Expand description

A simple cache for asset handles of type A. This stores WeakHandle, so it doesn’t keep the assets alive.

Implementations

source

impl<A> Cache<A>where
A: Clone,

source

pub fn new() -> Self

Creates a new Cache and initializes it with the default values.

source

pub fn insert<K: Into<String>>(
 &mut self,
 key: K,
 asset: &Handle<A>
) -> Option<WeakHandle<A>>

Inserts an asset with a given key and returns the old value (if any).

source

pub fn get<K>(&self, key: &K) -> Option<Handle<A>>where
K: ?Sized + Hash + Eq,
String: Borrow<K>,

Retrieves an asset handle using a given key.

source

pub fn clear_dead<F>(&mut self)

Deletes all cached handles which are invalid.

source

pub fn clear_all(&mut self)

Clears all values.
