Struct Job 

pub struct Job<T: Send + 'static> { /* private fields */ }

A single closure running on its own thread. Create with Job::spawn, reap with Job::join. Dropping a Job without joining detaches the thread (the closure runs to completion but its result and any panic are lost) — the overlap pattern always joins, so prefer explicit Job::join.

Implementations

impl<T: Send + 'static> Job<T>

pub fn spawn<F>(f: F) -> Self

where F: FnOnce() -> T + Send + 'static,

Spawn f on a fresh background thread and return immediately. The caller keeps working; call Job::join later to block for the result.

pub fn join(self) -> Result<T>

Block until the job finishes and return its value. A panic inside the job is surfaced as Err (identical semantics to JoinHandle::join) rather than aborting the caller.
