Struct ProviderCircuits 

pub struct ProviderCircuits(/* private fields */);

Every provider’s breaker state, as a world resource.

Written by the (serial) collect system and read by dispatch, so plain Res/ResMut access is enough - no interior mutability, no locks.

Implementations

impl ProviderCircuits

pub fn record_failure( &mut self, provider: &str, reason: UnavailableReason, now: i64, policy: &CircuitPolicy, ) -> bool

Count a provider-fatal failure against provider.

Returns true on the transition into the open state, so the caller can log and alert exactly once rather than on every subsequent failure.

pub fn record_success(&mut self, provider: &str)

Forget provider’s failures. Any success proves it is serving again.

pub fn is_open(&self, provider: &str, now: i64, policy: &CircuitPolicy) -> bool

Whether provider should be skipped right now.

False once the cooldown has elapsed, which is what makes the next request a probe without needing a distinct half-open state.

pub fn open_circuits( &self, now: i64, policy: &CircuitPolicy, ) -> Vec<ProviderCircuitState>

Every currently-open circuit, provider-sorted so the rendering is stable across ticks (a HashMap iteration order is not).

Trait Implementations

impl Clone for ProviderCircuits

fn clone(&self) -> ProviderCircuits

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Component for ProviderCircuits

where Self: Send + Sync + 'static,

const STORAGE_TYPE: StorageType = bevy_ecs::component::StorageType::SparseSet

A constant indicating the storage type used for this component.

type Mutability = Mutable

A marker type to assist Bevy with determining if this component is mutable, or immutable. Mutable components will have Component<Mutability = Mutable>, while immutable components will instead have Component<Mutability = Immutable>.

fn register_required_components( _requiree: ComponentId, required_components: &mut RequiredComponentsRegistrator<'_, '_>, )

Registers required components.

fn clone_behavior() -> ComponentCloneBehavior

Called when registering this component, allowing to override clone function (or disable cloning altogether) for this component.

fn relationship_accessor() -> Option<ComponentRelationshipAccessor<Self>>

Returns ComponentRelationshipAccessor required for working with relationships in dynamic contexts.

fn on_add() -> Option<for<'w> fn(DeferredWorld<'w>, HookContext)>

Gets the on_add ComponentHook for this Component if one is defined.

fn on_insert() -> Option<for<'w> fn(DeferredWorld<'w>, HookContext)>

Gets the on_insert ComponentHook for this Component if one is defined.

fn on_discard() -> Option<for<'w> fn(DeferredWorld<'w>, HookContext)>

Gets the on_discard ComponentHook for this Component if one is defined.

fn on_remove() -> Option<for<'w> fn(DeferredWorld<'w>, HookContext)>

Gets the on_remove ComponentHook for this Component if one is defined.

fn on_despawn() -> Option<for<'w> fn(DeferredWorld<'w>, HookContext)>

Gets the on_despawn ComponentHook for this Component if one is defined.

fn map_entities<E>(_this: &mut Self, _mapper: &mut E)

where E: EntityMapper,

Maps the entities on this component using the given EntityMapper. This is used to remap entities in contexts like scenes and entity cloning. When deriving Component, this is populated by annotating fields containing entities with #[entities]

impl Debug for ProviderCircuits

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for ProviderCircuits

fn default() -> ProviderCircuits

Returns the “default value” for a type.

impl Resource for ProviderCircuits

where Self: Send + Sync + 'static,
