Struct Assets 

pub struct Assets<T: Asset> { /* private fields */ }

A Resource that stores Assets of a given type

Each asset is mapped by an unique HandleId, allowing any Handle with the same HandleId to access it. One asset remain loaded as long as a Strong handle to that asset exists.

To get a reference to an asset without forcing it to stay loadid you can use a Weak handle

Implementations

impl<T: Asset> Assets<T>

pub fn contains(&self, handle: &Handle<T>) -> bool

Checks if an asset exists for the given handle

pub fn get(&self, handle: &Handle<T>) -> Option<&T>

Get an asset reference for the given handle

pub fn get_mut(&mut self, handle: &Handle<T>) -> Option<&mut T>

Get a mutable asset reference for the given handle

pub fn iter(&self) -> impl Iterator<Item = (&HandleId, &T)>

Gets an iterator over the assets in the storage

pub fn iter_mut(&mut self) -> impl Iterator<Item = (&HandleId, &mut T)>

Gets a mutable iterator over the assets in the storage

pub fn add(&mut self, asset: T) -> Handle<T>

Add an asset to the storage returning a strong handle to that asset

pub fn set(&mut self, handle: Handle<T>, asset: T) -> Handle<T>

Add/Replace the asset pointed by the given handle returning a strong handle to that asset

pub fn set_untracked(&mut self, handle_id: HandleId, asset: T)

Add/Replace the asset pointed by the given handle

pub fn remove<H: Into<HandleId>>(&mut self, handle: H) -> Option<T>

Remove the asset pointed by the given handle from the storage

The asset is returned

pub fn len(&self) -> usize

Gets the number of assets in the storage

pub fn is_empty(&self) -> bool

Returns true if there are no stored assets
