Struct MemoryNotification 

pub struct MemoryNotification { /* private fields */ }

The in-memory backend’s notification: a count of its raisings, which a thread can wait to see pass a value it has seen. Clones share one count, and each keeps its own record of how many raisings its own waits have seen, which starts at none – so a raising before a notification’s first wait is seen by it, as the Windows ring’s setup signal makes one that was raised before the wait began seen.

Implementations

impl MemoryNotification

pub fn raised(&self) -> u64

How many times it has been raised.

pub fn wait_past(&self, seen: u64, timeout: Duration) -> u64

Wait up to timeout for it to have been raised more than seen times; the count then.

Trait Implementations

impl Clone for MemoryNotification

fn clone(&self) -> MemoryNotification

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for MemoryNotification

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl Default for MemoryNotification

fn default() -> MemoryNotification

Returns the “default value” for a type.

impl Waitable for MemoryNotification

fn wait(&mut self, timeout: Option<Duration>) -> Result<bool, Error>

Wait for the notification to have been raised since the last wait that saw it, for up to timeout – None is no limit and Duration::ZERO only asks. Whether it was.
