Struct SupervisorBuilder 

pub struct SupervisorBuilder { /* private fields */ }

Builds a Supervisor with configurable parameters.

with_task() and configuration methods can be called in any order; task restart settings are applied uniformly at build() time.

Implementations

impl SupervisorBuilder

pub fn new() -> Self

pub fn with_task(self, name: &str, task: impl SupervisedTask + Clone) -> Self

pub fn with_max_backoff_exponent(self, exponent: u32) -> Self

Caps the exponent in the backoff formula: delay = base_restart_delay * 2^min(attempt, max_backoff_exponent).

pub fn with_health_check_interval(self, interval: Duration) -> Self

pub fn with_max_restart_attempts(self, attempts: u32) -> Self

pub fn with_unlimited_restarts(self) -> Self

pub fn with_base_restart_delay(self, delay: Duration) -> Self

pub fn with_task_being_stable_after(self, delay: Duration) -> Self

Once a task has been healthy for this long, its restart counter resets to zero.

pub fn with_dead_tasks_threshold( self, threshold_percentage: Option<f64>, ) -> Self

Shuts down the supervisor if the fraction of dead tasks exceeds threshold_percentage (0.0 – 1.0). None disables the check.

pub fn build(self) -> Supervisor
