Struct ChildShutdownPhases 

pub struct ChildShutdownPhases<B, Available, Phases> { /* private fields */ }

Inferred builder for statically complete child shutdown phases.

Implementations

impl<B, Available, Phases> ChildShutdownPhases<B, Available, Phases>

where B: Behavior,

pub fn shutdown_phase<Role>( self, _: Role, ) -> ChildShutdownPhases<B, <Available as AssignAt<<B as ResolveChildOccurrence<Role>>::Position>>::Assigned, Phase<Role, Phases>>

where B: ResolveChildOccurrence<Role>, Available: AssignAt<<B as ResolveChildOccurrence<Role>>::Position>,

Append one child as the next shutdown phase.

Foreign roles, roles declared for another application, wrongly typed roles, and duplicate roles have no applicable implementation.

A duplicate role is rejected independently:

struct Worker;
#[behavior::behavior(addr = behavior::MailAddr, message = behavior::Never)]
impl Worker {
    fn receive(&mut self, _: behavior::MailAddr, message: behavior::Never) -> behavior::BehaviorActed<Self> {
        match message {}
    }
}
type ManagedWorker = behavior_actors::StopOnShutdown<Worker>;
struct Application;
#[behavior::behavior(addr = behavior::MailAddr, message = behavior::Never, births = {
    store: ManagedWorker,
    gateway: ManagedWorker,
}, creation_settlements = retain_for_retirement)]
impl Application {
    fn receive(&mut self, _: behavior::MailAddr, message: behavior::Never) -> behavior::BehaviorActed<Self> {
        match message {}
    }
}
let _ = behavior_actors::shutdown_after_children(Application)
    .shutdown_phase(ApplicationChild::Store)
    .shutdown_phase(ApplicationChild::Store);

A role that belongs to no child declaration is rejected independently:

struct Worker;
#[behavior::behavior(addr = behavior::MailAddr, message = behavior::Never)]
impl Worker {
    fn receive(&mut self, _: behavior::MailAddr, message: behavior::Never) -> behavior::BehaviorActed<Self> {
        match message {}
    }
}
type ManagedWorker = behavior_actors::StopOnShutdown<Worker>;
struct Application;
#[behavior::behavior(addr = behavior::MailAddr, message = behavior::Never, births = {
    store: ManagedWorker,
    gateway: ManagedWorker,
}, creation_settlements = retain_for_retirement)]
impl Application {
    fn receive(&mut self, _: behavior::MailAddr, message: behavior::Never) -> behavior::BehaviorActed<Self> {
        match message {}
    }
}
struct ForeignRole;
let _ = behavior_actors::shutdown_after_children(Application).shutdown_phase(ForeignRole);

A route value cannot stand in for its declared role:

struct Worker;
#[behavior::behavior(addr = behavior::MailAddr, message = behavior::Never)]
impl Worker {
    fn receive(&mut self, _: behavior::MailAddr, message: behavior::Never) -> behavior::BehaviorActed<Self> {
        match message {}
    }
}
type ManagedWorker = behavior_actors::StopOnShutdown<Worker>;
struct Application;
#[behavior::behavior(addr = behavior::MailAddr, message = behavior::Never, births = {
    store: ManagedWorker,
    gateway: ManagedWorker,
}, creation_settlements = retain_for_retirement)]
impl Application {
    fn receive(&mut self, _: behavior::MailAddr, message: behavior::Never) -> behavior::BehaviorActed<Self> {
        match message {}
    }
}
let routes = ApplicationChildrenRoutes::new(1, 2);
let _ = behavior_actors::shutdown_after_children(Application).shutdown_phase(routes.store);

impl<B, Available, Phases> ChildShutdownPhases<B, Available, Phases>

where B: Behavior, B::Birth: BirthMode, Available: AllAssigned, <B::Birth as BirthMode>::Child: ChildOccurrenceProduct<ShutdownTargets<B>>, Phases: BuildShutdownPlan<B, ChildOccurrences<<<B as Behavior>::Birth as BirthMode>::Child, ShutdownTargets<B>>>, ChildOccurrences<<<B as Behavior>::Birth as BirthMode>::Child, ShutdownTargets<B>>: Selection<Addr = BehaviorAddr<B>> + Copy, <BehaviorAddr<B> as Address>::Nonce: Copy + Eq,

pub fn finish( self, ) -> HeterogeneousShutdownCoordinator<ChildShutdownPlan<B, Phases>, ChildOccurrences<<<B as Behavior>::Birth as BirthMode>::Child, ShutdownTargets<B>>>

where ChildShutdownPlan<B, Phases>: Behavior<Protocol = B::Protocol>,

Complete the application after proving that every child role occurs in exactly one declared phase.

The final actor’s source-indexed event ingress carries the plan through arbitrary outer layers without exposing a structural path.

struct Worker;
#[behavior::behavior(addr = behavior::MailAddr, message = behavior::Never)]
impl Worker {
    fn receive(&mut self, _: behavior::MailAddr, message: behavior::Never) -> behavior::BehaviorActed<Self> {
        match message {}
    }
}
type ManagedWorker = behavior_actors::StopOnShutdown<Worker>;
struct Application;
#[behavior::behavior(addr = behavior::MailAddr, message = behavior::Never, births = {
    store: ManagedWorker,
    gateway: ManagedWorker,
}, creation_settlements = retain_for_retirement)]
impl Application {
    fn receive(&mut self, _: behavior::MailAddr, message: behavior::Never) -> behavior::BehaviorActed<Self> {
        match message {}
    }
}
// `gateway` remains unassigned, so `finish` does not exist here.
let incomplete = behavior_actors::shutdown_after_children(Application)
    .shutdown_phase(ApplicationChild::Store)
    .finish();
