}Expand description
Additional methods for RwLocks which support upgradable locks and locking
with timeouts.
Required Methods§
sourcefn try_lock_upgradable_for(&self, timeout: Self::Duration) -> bool
fn try_lock_upgradable_for(&self, timeout: Self::Duration) -> bool
Attempts to acquire an upgradable lock until a timeout is reached.
sourcefn try_lock_upgradable_until(&self, timeout: Self::Instant) -> bool
fn try_lock_upgradable_until(&self, timeout: Self::Instant) -> bool
Attempts to acquire an upgradable lock until a timeout is reached.
sourceunsafe fn try_upgrade_for(&self, timeout: Self::Duration) -> bool
unsafe fn try_upgrade_for(&self, timeout: Self::Duration) -> bool
Attempts to upgrade an upgradable lock to an exclusive lock until a timeout is reached.
§Safety
This method may only be called if an upgradable lock is held in the current context.
sourceunsafe fn try_upgrade_until(&self, timeout: Self::Instant) -> bool
unsafe fn try_upgrade_until(&self, timeout: Self::Instant) -> bool
Attempts to upgrade an upgradable lock to an exclusive lock until a timeout is reached.
§Safety
This method may only be called if an upgradable lock is held in the current context.
Object Safety§
This trait is not object safe.
