Struct RestartStrategy 

pub struct RestartStrategy { /* private fields */ }

Restart strategy for a supervisor.

Defaults to one-to-one mode (only restart the failed process) and a restart intensity of 1 over a period of 5 seconds.

Restarts and permanent failure

A supervisor will allow up to intensity process restarts, across all child processes, over a given period. When this limit is exceeded, the supervisor will stop all child processes and return an error itself, indicating that the supervisor has failed overall.

Permanent failure bubbles up to the parent supervisor, until reaching the root supervisor. Once permanent failure reaches the root supervisor, and the root supervisor exceeds its own restart limits, the root supervisor will fail and cease execution.

Implementations

impl RestartStrategy

pub const fn new(mode: RestartMode, intensity: usize, period: Duration) -> Self

Creates a new RestartStrategy with the given mode, intensity, and period.

pub fn one_to_one() -> Self

Creates a new RestartStrategy with the one-to-one restart mode, and the default intensity/period.

pub fn one_for_all() -> Self

Creates a new RestartStrategy with the one-for-all restart mode, and the default intensity/period.

pub const fn with_intensity_and_period( self, intensity: usize, period: Duration, ) -> Self

Sets the restart intensity and period for the strategy.
