Additional methods for RwLocks which support upgradable locks and locking with timeouts.

Required Methods

fn try_lock_upgradable_for(&self, timeout: Self::Duration) -> bool

Attempts to acquire an upgradable lock until a timeout is reached.

fn try_lock_upgradable_until(&self, timeout: Self::Instant) -> bool

Attempts to acquire an upgradable lock until a timeout is reached.

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.

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.
