CrossProcessLockKind

matrix_sdk::cross_process_lock

Enum CrossProcessLockKind 

pub enum CrossProcessLockKind {
    Clean(CrossProcessLockGuard),
    Dirty(CrossProcessLockGuard),
}
Expand description

Represent a successful result of a locking attempt, either by CrossProcessLock::try_lock_once or CrossProcessLock::spin_lock.

Variants§

§

Clean(CrossProcessLockGuard)

The lock has been obtained successfully, all good.

§

Dirty(CrossProcessLockGuard)

The lock has been obtained successfully, but the lock is dirty!

This holder has obtained this cross-process lock once, then another holder has obtained this cross-process lock before this holder obtained it again. The lock is marked as dirty. It means the value protected by the cross-process lock may need to be reloaded if synchronisation is important.

Until CrossProcessLock::clear_dirty is called, CrossProcessLock::is_dirty, CrossProcessLock::try_lock_once and CrossProcessLock::spin_lock will report the lock as dirty. Put it differently: dirty once, dirty forever, unless CrossProcessLock::clear_dirty is called.
