Struct shine_ecs::resources::unnamed::ReadStore

pub struct ReadStore<'a, D> where
    D: 'static,  { /* fields omitted */ }

Grant immutable access to a (unnamed) store inside a System

Methods from Deref<Target = Store<D>>

pub fn read(&self) -> ReadGuard<D>

Trait Implementations

impl<'a, D> Deref for ReadStore<'a, D> where
    D: 'static, 

type Target = Store<D>

The resulting type after dereferencing.

fn deref(&self) -> &Self::Target

Dereferences the value.

impl<'a, D> SystemData<'a> for ReadStore<'a, D> where
    D: 'static, 

fn setup(_: &mut World)

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

fn fetch(res: &'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.
