Trait SceneEmitter 

pub trait SceneEmitter: Send + Sync {
    // Required method
    fn emit(
        &self,
        context: SceneFrameContext,
        props: &Value,
        scene: &mut Scene,
    ) -> Result<(), CompositionError>;
}

Shared primitive contract for media, shapes, captions, transitions, and apps.

Emitters append nodes to the supplied scene and can be nested through SceneSequence, SceneFreeze, SceneGroup, and SceneStack.

Required Methods

fn emit( &self, context: SceneFrameContext, props: &Value, scene: &mut Scene, ) -> Result<(), CompositionError>

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
