Struct JobSpec 

pub struct JobSpec { /* private fields */ }

Schedule for a job submitted via ActorSystem::run_job.

• max_iter — cap on iterations. None = run forever (until abort_job or the actor disappears). Some(n) exits after n successful iterations.
• interval — wait between iterations. None is a single-shot job (max_iter is forced to Some(1) in new).
• start_at — earliest moment the first iteration may run. If in the past, the job starts immediately. If in the future, the job loop sleeps until then before the first dispatch.

Implementations

impl JobSpec

pub fn new( max_iter: Option<usize>, interval: Option<Duration>, start_at: SystemTime, ) -> Self

Build a JobSpec. If interval is None, max_iter is forced to Some(1) regardless of the value you pass — single-shot jobs always run exactly once.

pub fn max_iter(&self) -> Option<usize>

Maximum number of iterations, or None for infinite.

pub fn start_at(&self) -> SystemTime

Earliest moment the first iteration may run.

pub fn interval(&self) -> Option<Duration>

Time between iterations, or None for single-shot.

Trait Implementations

impl Clone for JobSpec

fn clone(&self) -> JobSpec

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for JobSpec

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for JobSpec

fn default() -> Self

Single-shot, runs immediately. Equivalent to JobSpec::new(Some(1), None, SystemTime::now()).
