Trait springtime_di::component::ComponentDowncast

pub trait ComponentDowncast<C: Component>: Injectable {
    // Required method
    fn downcast(
        source: ComponentInstanceAnyPtr
    ) -> Result<ComponentInstancePtr<Self>, ComponentInstanceAnyPtr>;
}

Helper trait for traits implemented by components, thus allowing injection of components based on dyn Trait types. The type C refers to a concrete component type. Typically automatically derived when using the #[component_alias] attribute.

Required Methods

fn downcast( source: ComponentInstanceAnyPtr ) -> Result<ComponentInstancePtr<Self>, ComponentInstanceAnyPtr>
