Trait AssetServerCacheExt 

pub trait AssetServerCacheExt {
    // Required method
    fn load_cached<A: Asset>(
        &self,
        manifest: &CacheManifest,
        config: &CacheConfig,
        key: &str,
    ) -> Result<Handle<A>, CacheError>;
}

Extension trait that adds cache-aware loading to AssetServer.

Example

use bevy_cache::AssetServerCacheExt;

fn setup(
    asset_server: Res<AssetServer>,
    manifest: Res<CacheManifest>,
    config: Res<CacheConfig>,
) {
    let handle: Handle<Image> = asset_server
        .load_cached(&manifest, &config, "scene_thumb")
        .unwrap_or_else(|_| regenerate_thumbnail(&asset_server));
}

Required Methods

fn load_cached<A: Asset>( &self, manifest: &CacheManifest, config: &CacheConfig, key: &str, ) -> Result<Handle<A>, CacheError>

Load a cached asset by key.

Returns Ok(Handle<A>) when the cache file is present, or CacheError::NotFound when there is no manifest entry or the file was deleted from disk.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
