Struct DaemonServices 

pub struct DaemonServices<'w> {
    pub policy: Option<Res<'w, PolicyGate>>,
    pub script_rules: Option<Res<'w, GateScriptRules>>,
    pub hub: Option<Res<'w, InteractionHub>>,
    pub gate_stage: Option<Res<'w, GatePromptStage>>,
    pub persist: Option<Res<'w, PersistenceStage>>,
    pub sink: Option<Res<'w, WorldEventSink>>,
}

The resources the daemon installs, which a bare world does not have.

Every field is optional because lev run drives these same systems with no daemon behind them: no gate lane to prompt through, no persistence lane, no event sink. Bundled as one SystemParam so a system’s signature stays about what it queries rather than listing the six things that might be wired.

Fields

policy: Option<Res<'w, PolicyGate>>

The taint-gate policy, when one is configured.

script_rules: Option<Res<'w, GateScriptRules>>

Rhai rules the gate consults before blocking.

hub: Option<Res<'w, InteractionHub>>

The hub a blocked call can prompt through.

gate_stage: Option<Res<'w, GatePromptStage>>

The lane a gate prompt’s answer comes back on.

persist: Option<Res<'w, PersistenceStage>>

The lane run state is written on.

sink: Option<Res<'w, WorldEventSink>>

Where world events are broadcast.

Trait Implementations

impl<'w, 's> ReadOnlySystemParam for DaemonServices<'w>

where Option<Res<'w, PolicyGate>>: ReadOnlySystemParam, Option<Res<'w, GateScriptRules>>: ReadOnlySystemParam, Option<Res<'w, InteractionHub>>: ReadOnlySystemParam, Option<Res<'w, GatePromptStage>>: ReadOnlySystemParam, Option<Res<'w, PersistenceStage>>: ReadOnlySystemParam, Option<Res<'w, WorldEventSink>>: ReadOnlySystemParam,

impl SystemParam for DaemonServices<'_>

type State = FetchState

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

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

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) -> Self::State

Creates a new instance of this param’s State.

fn init_access( state: &Self::State, system_meta: &mut SystemMeta, component_access_set: &mut FilteredAccessSet, world: &mut World, )

Registers any World access used by this SystemParam.

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 ApplyDeferred.

fn queue( state: &mut Self::State, system_meta: &SystemMeta, world: DeferredWorld<'_>, )

Queues any deferred mutations to be applied at the next ApplyDeferred.

unsafe fn get_param<'w, 's>( state: &'s mut Self::State, system_meta: &SystemMeta, world: UnsafeWorldCell<'w>, change_tick: Tick, ) -> Result<Self::Item<'w, 's>, SystemParamValidationError>

Creates a parameter to be passed into a SystemParamFunction.
