Trait AssetLoader 

pub trait AssetLoader {
    // Required method
    fn load_asset(
        &self,
        handler: &mut dyn AssetCreationHandler,
        identifier: &str,
    ) -> Option<AnyHandle<dyn Any>>;
}

An AssetLoader loads an asset given its name, with help from an AssetCreationHandler. Some AssetLoaders implement special behaviour, such as caching or combining multiple child loaders.

Required Methods

fn load_asset( &self, handler: &mut dyn AssetCreationHandler, identifier: &str, ) -> Option<AnyHandle<dyn Any>>

Load an asset with the given identifier.

Returns None if the asset could not be found or failed to serialize.

Implementations on Foreign Types

impl AssetLoader for Vec<Box<dyn AssetLoader>>

A Vec<Box> or similar structure can act as a combined loader over its elements, querying them one by one. The boxed_vec! macro can help with this. Prefer this over the use of a CombinedLoader.

fn load_asset( &self, handler: &mut dyn AssetCreationHandler, identifier: &str, ) -> Option<AnyHandle<dyn Any>>

impl AssetLoader for HashMap<String, AnyHandle<dyn Any>>

A simple HashMap can act as a loader for a set of values in memory.

fn load_asset( &self, _handler: &mut dyn AssetCreationHandler, identifier: &str, ) -> Option<AnyHandle<dyn Any>>

impl AssetLoader for PathBuf

A PathBuf can act as a loader for files relative to the directory it points to.

fn load_asset( &self, handler: &mut dyn AssetCreationHandler, identifier: &str, ) -> Option<AnyHandle<dyn Any>>

Implementors

impl<Loader> AssetLoader for CachedLoader<Loader>

where Loader: AssetLoader,

Implement AssetLoader for the CachedLoader.
