Trait Implementations

impl<'a> SystemData<'a> for ReadData<'a>

where Entities<'a>: SystemData<'a>, Read<'a, IdMaps>: SystemData<'a>, Events<'a>: SystemData<'a>, ReadExpect<'a, TerrainGrid>: SystemData<'a>, ReadStorage<'a, Pos>: SystemData<'a>, ReadStorage<'a, Body>: SystemData<'a>, ReadStorage<'a, Scale>: SystemData<'a>, ReadStorage<'a, Collider>: SystemData<'a>, ReadStorage<'a, Uid>: SystemData<'a>, ReadStorage<'a, Health>: SystemData<'a>,

fn setup(world: &mut World)

Sets up the system data for fetching it from the World.

fn fetch(world: &'a World) -> Self

Fetches the system data from World. Note that this is only specified for one concrete lifetime 'a, you need to implement the SystemData trait for every possible lifetime.

fn reads() -> Vec<ResourceId>

Returns all read dependencies as fetched from Self::fetch.

fn writes() -> Vec<ResourceId>

Returns all write dependencies as fetched from Self::fetch.
