[−] Expand description

Additional methods for RwLocks which support locking with timeouts.

The Duration and Instant types are specified as associated types so that this trait is usable even in no_std environments.

Associated Types

type Duration[−]

Duration type used for try_lock_for.

type Instant[−]

Instant type used for try_lock_until.

Required methods

fn try_lock_shared_for(&self, timeout: Self::Duration) -> bool[−]

Attempts to acquire a shared lock until a timeout is reached.

fn try_lock_shared_until(&self, timeout: Self::Instant) -> bool[−]

Attempts to acquire a shared lock until a timeout is reached.

fn try_lock_exclusive_for(&self, timeout: Self::Duration) -> bool[−]

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

fn try_lock_exclusive_until(&self, timeout: Self::Instant) -> bool[−]

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