Enum SupervisorAction 

pub enum SupervisorAction {
    Restart,
    Escalate,
    Ignore,
}

The action a Supervisor takes when a child machine fails.

Variants

Restart

Restart the failed child machine from its initial state.

The child is re-initialized and begins executing again. Other children are unaffected (unless RestartStrategy::OneForAll or RestartStrategy::RestForOne is in effect).

Escalate

Stop the failed child and propagate the error up the supervision tree.

Use this when a child failure is unrecoverable and the parent supervisor (or the top-level caller) should handle it.

Ignore

Ignore the failure and let the child remain in its failed state.

The child is not restarted. This is appropriate for non-critical background tasks whose failure does not affect the overall system.
