pub struct Compose<B> { /* private fields */ }

Implementations

impl<S, O, Br, E> Compose<Pure<S, O, Br, E>>

where S: Handler<O, Br, E>, Br: BirthMode,

pub fn new(state: S) -> Compose<Pure<S, O, Br, E>>

impl<A, S, M, P, E> Compose<Machine<A, S, M, P, E>>

where A: Address, P: Copy + PartialEq,

pub fn machine( state: S, phase: P, on: fn(P, &mut S, &M) -> Result<Move<P>, E>, ) -> Compose<Machine<A, S, M, P, E>>

impl<S, A, M, Sends, Br, E, I, F> Compose<BehaviorFn<S, A, M, Sends, Br, E, I, F>>

where A: Address, Sends: SendAlgebra, Br: BirthMode, I: FnMut(&mut S) -> Result<Actions<A, Never, Sends, Br>, E>, F: FnMut(&mut S, A, M) -> Result<Actions<A, Never, Sends, Br>, E>,

pub fn from_fns( state: S, initialize: I, transition: F, ) -> Compose<BehaviorFn<S, A, M, Sends, Br, E, I, F>>

Define a concrete behavior from explicit initialization and user-event folds, ready for typed wrapper composition.

impl<B> Compose<B>

where B: Behavior,

pub fn from_behavior(behavior: B) -> Compose<B>

pub fn build(self) -> B

pub fn behavior(&self) -> &B

pub fn stop_on_shutdown(self) -> Compose<StopOnShutdown<B>>

Stop normally when a typed shutdown request is folded.

pub fn finalize_on_shutdown( self, finalize: fn(&mut B, ShutdownRequested) -> Result<Actions<<B as Behavior>::Addr, <B as Behavior>::Ph, <B as Behavior>::Sends, <B as Behavior>::Birth>, <B as Behavior>::Error>, ) -> Compose<FinalizeOnShutdown<B>>

Apply one final pure fold, retain its sends and creations, and stop normally regardless of the fold’s become verdict.

pub fn watch( self, peer: <B as Behavior>::Addr, on_stopped: fn(&mut B, <B as Behavior>::Addr, &Result<Exit<<B as Behavior>::Addr>, Crash>) -> Result<Step<Never, Exit<<B as Behavior>::Addr>>, <B as Behavior>::Error>, ) -> Compose<Watch<B>>

Observe a peer and apply a pure reaction when it stops.

pub fn deadline( self, when: Option<Instant>, on_reached: fn(&mut B) -> Result<Step<Never, Exit<<B as Behavior>::Addr>>, <B as Behavior>::Error>, ) -> Compose<Deadline<B>>

Apply a pure reaction when the given absolute time is reached.

Panics

Panics if one specification composes more than u64::MAX timer capabilities.

pub fn receive_timeout( self, after: Duration, on_elapsed: fn(&mut B) -> Result<Actions<<B as Behavior>::Addr, <B as Behavior>::Ph, <B as Behavior>::Sends, <B as Behavior>::Birth>, <B as Behavior>::Error>, ) -> Compose<ReceiveTimeout<B>>

Notify the behavior once after an idle period containing no successful user communication.

Initialization and each successful continuing user fold emit a relative schedule. Service events never reset inactivity. A matching delivery is consumed before on_elapsed runs, and a continuing reaction remains unarmed until another successful continuing user communication.

Panics

Panics if one specification composes more than u64::MAX timer capabilities.

pub fn stash( self, route: fn(&<B as Behavior>::Msg) -> StashRoute, ) -> Compose<Stash<B>>

where B: Behavior<Ph = Never>,

Hold messages selected by route and replay them on Release.

pub fn children<C>( self, fleet: (usize, fn(usize) -> C), ) -> Compose<Supervisor<B, C>>

where B: Behavior<Birth = Births<C>>, C: Behavior<Ph = Never, Addr = <B as Behavior>::Addr>, <<B as Behavior>::Addr as Address>::Nonce: From<u64>,

Create a supervised child topology. Concrete proxy and monitor types remain hidden in the returned typestate.

pub fn children_with_nonces<C>( self, nonces: fn(usize) -> <<B as Behavior>::Addr as Address>::Nonce, count: usize, build: fn(usize) -> C, ) -> Compose<Supervisor<B, C>>

where B: Behavior<Birth = Births<C>>, C: Behavior<Ph = Never, Addr = <B as Behavior>::Addr>,

impl<B, C> Compose<Supervisor<B, C>>

where C: Behavior<Ph = Never, Addr = <B as Behavior>::Addr>, B: Behavior<Birth = Births<C>>,

pub fn restart(self, strategy: Strategy) -> Compose<Supervisor<B, C>>

pub fn when(self, policy: RestartPolicy) -> Compose<Supervisor<B, C>>

pub fn within(self, maximum: u32, window: Duration) -> Compose<Supervisor<B, C>>

pub fn on_supervision_failure( self, reaction: fn(&mut B, &SupervisionFailure<<B as Behavior>::Addr>) -> Result<Step<Never, Exit<<B as Behavior>::Addr>>, <B as Behavior>::Error>, ) -> Compose<Supervisor<B, C>>

Apply a pure reaction when supervision can no longer preserve its child topology.

Trait Implementations

impl<B, A, Ph, Sends, Br> Behavior for Compose<B>

where A: Address, Sends: SendAlgebra, Br: BirthMode, B: Behavior<Addr = A, Ph = Ph, Sends = Sends, Birth = Br>,

type Addr = A

type Msg = <B as Behavior>::Msg

type Event = <B as Behavior>::Event

type Sends = Sends

type Ph = Ph

type Error = <B as Behavior>::Error

type Birth = Br

fn init(&mut self) -> Result<Actions<A, Ph, Sends, Br>, <B as Behavior>::Error>

Produce initialization actions before the first event is accepted.

fn transition( &mut self, event: <B as Behavior>::Event, ) -> Result<Actions<A, Ph, Sends, Br>, <B as Behavior>::Error>

Fold exactly one event into explicit actions and the next behavior.

fn receive( &mut self, from: Self::Addr, message: Self::Msg, ) -> Result<Actions<Self::Addr, Self::Ph, Self::Sends, Self::Birth>, Self::Error>

where Self: Sized,

Fold one user communication through the composed protocol.

fn on<Input>( &mut self, input: Input, ) -> Result<Actions<Self::Addr, Self::Ph, Self::Sends, Self::Birth>, Self::Error>

where Self: Sized, Self::Event: EventInput<Input>,

Inject one supported semantic input and fold it through this behavior.
