Struct RcuDomain

pub struct RcuDomain { /* private fields */ }

An RCU synchronization domain.

Implementations

impl RcuDomain

pub fn run<F, R>(self, f: F) -> R

where F: FnOnce() -> R,

Runs f in a critical section. Calls to synchronize or synchronize_blocking for the same RCU root will block until f returns.

In general, you should avoid blocking the thread in f, since that can slow calls to synchronize and can potentially cause deadlocks.

pub fn quiesce(self)

Quiesce the current thread.

This can speed up calls to synchronize or synchronize_blocking by allowing the RCU domain to skip issuing a membarrier if all threads are quiesced. In return, the first call to run after this will be slower, as it will need to issue a memory barrier to leave the quiesced state.

pub async fn quiesce_on_pending<Fut>(self, fut: Fut) -> Fut::Output

where Fut: Future,

Runs fut, calling quiesce on the current thread each time fut returns Poll::Pending.

pub async fn synchronize(self, sleep: impl AsyncFnMut(Duration))

Synchronizes the RCU domain, blocking asynchronously until all threads have exited their critical sections and observed the new sequence number.

sleep should be a function that sleeps for the specified duration.

pub fn synchronize_blocking(self)

Like synchronize, but blocks the current thread synchronously.
