Struct Supervising 

pub struct Supervising<B: Behavior, C: Behavior<Ph = Never, Addr = B::Addr>> { /* private fields */ }

Implementations

impl<B, C> Supervising<B, C>

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

pub fn new( inner: B, nonces: fn(usize) -> <B::Addr as Address>::Nonce, count: usize, build: fn(usize) -> C, strategy: Strategy, policy: RestartPolicy, max_restarts: u32, window: Duration, ) -> Self

Construct the concrete supervisor behavior hidden by Spec.

Panics

Panics only if a fleet index cannot be represented by u64.

pub fn with_strategy(self, strategy: Strategy) -> Self

pub fn with_policy(self, policy: RestartPolicy) -> Self

pub fn with_budget(self, max: u32, window: Duration) -> Self

pub fn with_failure_reaction( self, reaction: SupervisionFailureReaction<B>, ) -> Self

Replace the pure reaction used for typed supervision failures.

pub fn is_alive(&self, nonce: <B::Addr as Address>::Nonce) -> bool

Report whether a known supervised proxy is alive.

Panics

Panics when nonce is not part of this supervisor topology.

pub fn child_count(&self) -> usize

pub fn restarts_in_window(&self) -> usize
