Enum CurrentParkStart 

pub enum CurrentParkStart {
    Notified,
    Prepared(PreparedCurrentPark),
}

Result of beginning an externally queued current-thread park transaction.

OS wait subsystems use this after validating their condition under their own queue lock. The scheduler still owns the generation, deadline, and context switch transaction; callers own only publication and removal of their domain-specific waiter record.

Variants

Notified

A preceding wake was consumed, so no waiter may be published for this attempt.

Prepared(PreparedCurrentPark)

The current thread entered Parking and must be committed or cancelled.
