Struct RcuLock 

pub struct RcuLock<T, L = RcuLockLevel> { /* private fields */ }

A synchronization wrapper that combines an RCU primitive T with a lock at level L to serialize updates while permitting lock-free RCU reads.

Readers access the underlying RCU value without acquiring the mutex via the read methods on DynamicRcuLock. Writers must acquire the mutex via DynamicRcuLock::lock or DynamicRcuLock::try_lock to obtain an RcuLockGuard, which grants exclusive writer access to T.

Implementations

impl<T, L: LockLevel> RcuLock<T, L>

pub const fn new(rcu: T) -> Self

Creates a new RcuLock wrapping rcu.

Methods from Deref<Target = DynamicRcuLock<T>>

pub fn lock(&self) -> RcuLockGuard<'_, T>

Acquires the update lock and returns a guard that allows updating the RCU cell.

pub fn try_lock(&self) -> Option<RcuLockGuard<'_, T>>

Attempts to acquire the update lock without blocking.
