fn fmt(&self, f: &mut Formatter) -> Result[−]

Formats the value using the given formatter.

fn build(self, world: &mut World) -> UiTransformSystem[−]

Builds and returns a System.

impl<'a> System<'a> for UiTransformSystem[+]

[+] Show hidden undocumented items

type SystemData = (WriteStorage<'a, UiTransform>, ReadStorage<'a, Parent>, ReadExpect<'a, ScreenDimensions>, ReadExpect<'a, ParentHierarchy>)

The resource bundle required to execute this system.

fn run(&mut self, data: 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, world: &mut World)[−]

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

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

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