Enum CrossProcessLockState 

pub enum CrossProcessLockState {
    Clean(CrossProcessLockGuard),
    Dirty(CrossProcessLockGuard),
}

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.

Implementations

impl CrossProcessLockState

pub fn into_guard(self) -> CrossProcessLockGuard

Map this value into the inner CrossProcessLockGuard.

pub fn map<F, G>(self, mapper: F) -> MappedCrossProcessLockState<G>

where F: FnOnce(CrossProcessLockGuard) -> G,

Map this CrossProcessLockState into a MappedCrossProcessLockState.

This is helpful when one wants to create its own wrapper over CrossProcessLockGuard.

Trait Implementations

impl Debug for CrossProcessLockState

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

Formats the value using the given formatter.
