Enum RestartStrategy 

pub enum RestartStrategy {
    OneForOne,
    OneForAll,
    RestForOne,
}

Strategy that determines which children are restarted when one fails.

These strategies are modeled after Erlang/OTP supervisor behaviors and are used by SupervisorRuntime::restart_scope to compute the range of children to restart.

Variants

Given children [A, B, C, D, E] where C (index 2) fails:

Strategy	Restarted children
OneForOne	[C]
OneForAll	[A, B, C, D, E]
RestForOne	[C, D, E]

Variants

OneForOne

Restart only the failed child. Other children are unaffected.

This is the default strategy and is appropriate when children are independent of each other.

OneForAll

Restart all children when any single child fails.

Use this when children have interdependencies and a consistent group state is required.

RestForOne

Restart the failed child and all children started after it.

This is useful when later children depend on earlier ones: restarting from the failure point forward re-establishes the dependency chain without disturbing earlier, independent children.
