Enum ResumeError 

pub enum ResumeError {
    UnknownProcess(ProcessId),
    AlreadyStarted(ProcessId),
    WaitOrderViolated(ProcessId),
}

Errors ResumeDriver returns instead of ever panicking or silently dropping a call — this crate’s correctness posture requires a loud, typed error on every rejected/invalid call, never a silent no-op.

Variants

UnknownProcess(ProcessId)

AlreadyStarted(ProcessId)

SC-059: ResumeDriver::start was called a second time for a ProcessId whose ProcessDescriptor::started CAS was already true — rejected loudly rather than calling resume(Start) twice.

WaitOrderViolated(ProcessId)

NEW (Task 9, B-sched wave, ledger SC-125). A wait_order(...)- suspended parent observed ProcessId complete out of its own declared order — returned by ResumeDriver::on_child_done instead of ever silently accepting the reordering or resuming the parent via ResumeArg::WaitOrderSatisfied anyway.

fn description(&self) -> &str

👎Deprecated since 1.42.0:

use the Display impl or to_string()
