Struct Supervisor 

pub struct Supervisor { /* private fields */ }

Owns the host’s background jobs over a single Spawn backend.

Implementations

impl Supervisor

pub fn new(spawn: Arc<dyn Spawn>) -> Self

Create a supervisor backed by spawn (production batpak::store::ThreadSpawn or a test scheduler).

pub fn spawn( &mut self, name: impl Into<String>, stack_size: Option<usize>, body: Box<dyn FnOnce() + Send + 'static>, ) -> Result<(), SpawnError>

Spawn body as a named supervised job.

Errors

SpawnError if the backing Spawn could not start the body.

pub fn job_count(&self) -> usize

Number of jobs the supervisor is tracking (finished or running).

pub fn statuses(&self) -> Vec<(String, JobStatus)>

The non-blocking status of every tracked job, in spawn order.

pub fn join_all(&mut self) -> Vec<(String, Result<(), JoinError>)>

Join every tracked job, blocking until each finishes, and return each job’s name with its join outcome in spawn order. The supervisor is left empty.

A job whose body never returns blocks here forever — the generic supervisor cannot cancel a body it did not author. Modules that own long-lived work signal it to wind down from a shutdown hook (which the host runs before this join).
