Trait CompositingLayerAnimation 

pub trait CompositingLayerAnimation:
    Clone
    + Default
    + 'static {
    // Required methods
    fn advance(&mut self, elapsed_ms: f32) -> bool;
    fn compositing_layer_spec(&self) -> CompositingLayerSpec;

    // Provided methods
    fn wants_frame(&self) -> bool { ... }
    fn frame_interval_ms(&self) -> u64 { ... }
}

Application-owned animation state for a retained compositing layer.

The framework advances this state and applies the resulting composition properties directly to the retained node. Static layer children are not rebuilt when only the spec changes.

Required Methods

fn advance(&mut self, elapsed_ms: f32) -> bool

fn compositing_layer_spec(&self) -> CompositingLayerSpec

Provided Methods

fn wants_frame(&self) -> bool

fn frame_interval_ms(&self) -> u64

Dyn Compatibility

This trait is not dyn compatible.

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