Struct MemoryOps 

pub struct MemoryOps {
    ops: Option<Arc<dyn SharedMemoryOps + Send + Sync>>,
}

Shared memory operations that do not hold the underlying memory alive.

This handle is intended for operations, such as waking atomic waiters, that may be attempted after the original memory owner has started shutting down.

Fields

ops: Option<Arc<dyn SharedMemoryOps + Send + Sync>>

Implementations

impl MemoryOps

fn shared_ops( &self, ) -> Result<&(dyn SharedMemoryOps + Send + Sync), AtomicsError>

pub fn notify( &self, location: MemoryLocation, count: u32, ) -> Result<u32, AtomicsError>

Notify up to count waiters waiting for the memory location.

pub fn wait( &self, location: MemoryLocation, timeout: Option<Duration>, ) -> Result<u32, AtomicsError>

Wait for the memory location to be notified.

pub fn disable_atomics(&self) -> Result<(), AtomicsError>

Disable atomics for this memory if it is still alive.

All subsequent atomic wait calls will produce a trap.

pub fn wake_all_atomic_waiters(&self) -> Result<(), AtomicsError>

Wake up all atomic waiters if the memory is still alive.
