Trait Implementations

impl<P> Default for SceneGraphSystem<P>

fn default() -> Self

Returns the "default value" for a type.

impl<'system, P> System<'system> for SceneGraphSystem<P> where     P: Parent,     P::Storage: Default + Tracked,

type SystemData = (Entities<'system>, ReadStorage<'system, P>, Write<'system, SceneGraph<P>, SceneGraphSetupHandler<P>>)

The resource bundle required to execute this system.

fn run(&mut self, (entities, parents, scene_graph): Self::SystemData)

Executes the system with the required system data.

fn running_time(&self) -> RunningTime

Returns a hint how long the system needs for running. This is used to optimize the way they're executed (might allow more parallelization).

fn accessor(&'b self) -> AccessorCow<'a, 'b, Self>

Return the accessor from the [SystemData].

fn setup(&mut self, res: &mut Resources)

Sets up the Resources using Self::SystemData::setup.
