Struct bones_lib::prelude::Res

pub struct Res<'a, T>(/* private fields */)
where
    T: HasSchema;

SystemParam for getting read access to a resource.

Use ResInit if you want to automatically initialize the resource.

Trait Implementations

impl<'a, T> Deref for Res<'a, T>

where T: HasSchema,

type Target = T

The resulting type after dereferencing.

fn deref(&self) -> &<Res<'a, T> as Deref>::Target

Dereferences the value.

impl<'a, T> SystemParam for Res<'a, T>

where T: HasSchema,

type State = AtomicResource<T>

The intermediate state for the parameter, that may be extracted from the world.

type Param<'p> = Res<'p, T>

The type of the parameter, ranging over the lifetime of the intermediate state.

fn get_state(world: &World) -> <Res<'a, T> as SystemParam>::State

This is called to produce the intermediate state of the system parameter.

fn borrow<'s>( _world: &'s World, state: &'s mut <Res<'a, T> as SystemParam>::State, ) -> <Res<'a, T> as SystemParam>::Param<'s>

This is used create an instance of the system parame, possibly borrowed from the intermediate parameter state.
