Trait 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>

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.
