[−][src]Struct sixtyfps_corelib::graphics::TrackingRenderingPrimitive

pub struct TrackingRenderingPrimitive<Backend: GraphicsBackend> {
    pub primitive: Backend::LowLevelRenderingPrimitive,
    pub dependency_tracker: Pin<Box<PropertyTracker>>,
}

Holds a GraphicBackend's rendering primitive as well as a PropertyTracker that allows lazily re-creating the primitive if the properties needed to create it have changed.

Fields

primitive: Backend::LowLevelRenderingPrimitive

The rendering primitive that's being tracked.

dependency_tracker: Pin<Box<PropertyTracker>>

The property tracker that should be used to evaluate whether the primitive needs to be re-created or not.

Implementations

impl<Backend: GraphicsBackend> TrackingRenderingPrimitive<Backend>[src]

pub fn new(
    update_fn: impl FnOnce() -> Backend::LowLevelRenderingPrimitive
) -> Self[src]

Creates a new TrackingRenderingPrimitive by evaluating the provided update_fn once, storing the returned rendering primitive and initializing the dependency tracker.
