Trait Implementations

impl SystemParam for ContextSystemParams<'_, '_>

type State = FetchState

Used to store data which persists across invocations of a system.

type Item<'w, 's> = ContextSystemParams<'w, 's>

The item type returned when constructing this system param. The value of this associated type should be Self, instantiated with new lifetimes.

fn init_state(world: &mut World, system_meta: &mut SystemMeta) -> Self::State

Registers any [World] access used by this [SystemParam] and creates a new instance of this param’s State.

fn new_archetype( state: &mut Self::State, archetype: &Archetype, system_meta: &mut SystemMeta )

For the specified [Archetype], registers the components accessed by this [SystemParam] (if applicable).

fn apply(state: &mut Self::State, system_meta: &SystemMeta, world: &mut World)

Applies any deferred mutations stored in this [SystemParam]’s state. This is used to apply Commands during apply_system_buffers.

unsafe fn get_param<'w, 's>( state: &'s mut Self::State, system_meta: &SystemMeta, world: &'w World, change_tick: u32 ) -> Self::Item<'w, 's>
