impl From<&AssetPath> for HandleId

[tguichaoua]

Objective

In AssetLoader::load(), I have an AssetPath to a dependency asset.
I get a handle to this dependency asset using LoadContext::get_handle() passing the AssetPath. But I also need to pass this AssetPath to LoadedAsset::with_dependency() later.

The current solution for this problem is either use clone(), but AssetPath may contains owned data.

let dependency_path: AssetPath = _;
let dependency = load_context.get_handle(dependency_path.clone());
// ...
load_context.set_default_asset(LoadedAsset::new(my_asset).with_dependency(dependency_path));

Or to use AssetPathId::from(&path) which is a bit verbose.

let dependency_path: AssetPath = _;
let dependency = load_context.get_handle(AssetPathId::from(&dependency_path));
// ...
load_context.set_default_asset(LoadedAsset::new(my_asset).with_dependency(dependency_path));

Ideal solution (introduced by this PR) is to pass a reference to get_handle().

let dependency_path: AssetPath = _;
let dependency = load_context.get_handle(&dependency_path);
// ...
load_context.set_default_asset(LoadedAsset::new(my_asset).with_dependency(dependency_path));

Solution

Implement From<&AssetPath> for HandleId

• Added: HandleId can be build from a reference to AssetPath.
