}

Abstract source for asset raw data.

Associated Types

type Error: Error + Send + Sync

Error that may occur during asset loading.

Required methods

fn find(&self, path: &str, asset: &str) -> BoxFuture<'_, Option<AssetId>>

Searches for the asset by given path. Returns Ok(Some(asset_data)) if asset is found and loaded successfully. Returns Ok(None) if asset is not found.

fn load(
    &self,
    id: AssetId
) -> BoxFuture<'_, Result<Option<AssetData>, Self::Error>>

Load asset data from this source. Returns Ok(Some(asset_data)) if asset is loaded successfully. Returns Ok(None) if asset is not found, allowing checking other sources.

fn update(
    &self,
    id: AssetId,
    version: u64
) -> BoxFuture<'_, Result<Option<AssetData>, Self::Error>>

Update asset data if newer is available.
