Module supervisor

Structs

Supervisor

The supervisor actor itself.
Spawns its children in post_start, listens for child failures, and restarts them if needed.
If meltdown occurs, it returns an error to end abnormally (thus skipping post_stop).

SupervisorArguments

The arguments needed to spawn the supervisor.

SupervisorOptions

Supervisor-level meltdown policy.

SupervisorState

Holds the supervisor’s live state: which children are running, how many times each child has failed, etc.

Enums

SupervisorMsg

Internal messages that instruct the supervisor to spawn a child, triggered by its meltdown logic.

SupervisorStrategy

The supervision strategy for this supervisor’s children.
