Trait AssetTransformer

    + 'static {
    type AssetInput: Asset;
    type AssetOutput: Asset;
    type Settings: Settings + Default + Serialize + for<'a> Deserialize<'a>;

    // Required method
    fn transform<'a>(
        &'a self,
        asset: TransformedAsset<Self::AssetInput>,
        settings: &'a Self::Settings,
    ) -> impl ConditionalSendFuture<Output = Result<TransformedAsset<Self::AssetOutput>, Self::Error>>;
}

Transforms an Asset of a given AssetTransformer::AssetInput type to an Asset of AssetTransformer::AssetOutput type.

Required Associated Types

type AssetInput: Asset

The Asset type which this AssetTransformer takes as and input.

type AssetOutput: Asset

The Asset type which this AssetTransformer outputs.

type Settings: Settings + Default + Serialize + for<'a> Deserialize<'a>

The settings type used by this AssetTransformer.

type Error: Into<Box<dyn Error + Send + Sync + 'static>>

The type of error which could be encountered by this transformer.

Required Methods

fn transform<'a>( &'a self, asset: TransformedAsset<Self::AssetInput>, settings: &'a Self::Settings, ) -> impl ConditionalSendFuture<Output = Result<TransformedAsset<Self::AssetOutput>, Self::Error>>

Transforms the given TransformedAsset to AssetTransformer::AssetOutput. The TransformedAsset’s labeled_assets can be altered to add new Labeled Sub-Assets The passed in settings can influence how the asset is transformed

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.
