Struct SupervisorStrategy 

pub struct SupervisorStrategy {
    pub kind: StrategyKind,
    pub max_retries: Option<u32>,
    pub within: Option<Duration>,
    pub decider: Decider,
}

Strategy applied to children of a supervising actor. Splits into OneForOne (each child handled independently) and AllForOne (one child’s failure restarts all siblings).

Fields

kind: StrategyKind

max_retries: Option<u32>

within: Option<Duration>

decider: Decider

Implementations

impl SupervisorStrategy

pub fn decide(&self, err: &str) -> Directive

pub fn on_max_retries(&self) -> Directive

Directive applied when Self::max_retries within Self::within is exceeded.

Defaults to Directive::Escalate — matching Akka’s behaviour: the parent supervisor decides the next step, and at the user-guardian root that is equivalent to stopping the cell. Override via a future builder method when per-strategy on-overflow behaviour is needed.
