Struct JobRegistry 

pub struct JobRegistry { /* private fields */ }

Shared job registry. Cheap to clone.

Implementations

impl JobRegistry

pub fn new() -> Self

Empty registry with next_id = 1.

pub fn create(&self, printer_name: String) -> JobRecord

Allocate a new pending job for printer_name. Returns a clone of the record so the caller can stash the JobId and cancel_flag without holding the registry lock.

pub fn get(&self, id: JobId) -> Option<JobRecord>

Look up a job by id. Returns a clone so the caller doesn’t hold the lock.

pub fn jobs_for_printer(&self, printer_name: &str) -> Vec<JobRecord>

All jobs that target the named printer. Order is allocation order.

pub fn set_state(&self, id: JobId, state: JobState)

Force a job into state. Stamps completed_at when crossing into a terminal state. No-op if the id doesn’t exist.

pub fn set_failure(&self, id: JobId, reasons: PrinterReason, message: String)

Mark a job as failed with IPP reasons + message.

pub fn cancel(&self, id: JobId) -> Option<JobState>

Request cancellation. Returns the new state, or None if no such job. Already-terminal jobs are left alone.
