Type parameters:

Methods

impl<P> HierarchySystem<P> where
    P: Component + Parent + Send + Sync + 'static,
    P::Storage: Tracked
[src]

pub fn new(world: &mut World) -> Self[src]

Trait Implementations

impl<'a, P> System<'a> for HierarchySystem<P> where
    P: Component + Parent + Send + Sync + 'static,
    P::Storage: Tracked
[src]

type SystemData = (ParentData<'a, P>, WriteExpect<'a, Hierarchy<P>>)

The resource bundle required to execute this system. Read more

fn running_time(&self) -> RunningTime[src]

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

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

Return the accessor from the [SystemData].

fn setup(&mut self, world: &mut World)[src]

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

fn dispose(self, world: &mut World)[src]

Performs clean up that requires resources from the World. This commonly removes components from world which depend on external resources. Read more
