Struct ReadinessWatched 

pub struct ReadinessWatched {
    watchers: RefCell<Vec<Weak<ReadinessWatcher>>>,
    ready_clock: RefCell<VClock>,
}

Data about a file description that can be watched for readiness (meant to be stored inside said file description).

Fields

watchers: RefCell<Vec<Weak<ReadinessWatcher>>>

List of readiness watchers that are interested in us.

ready_clock: RefCell<VClock>

Vector clock for the most recent change to our readiness. (Ideally this would be one clock per readiness flag, but we’re not bothering with that.)

Implementations

impl ReadinessWatched

fn insert(&self, watcher: &Rc<ReadinessWatcher>)

fn remove(&self, watcher: &Rc<ReadinessWatcher>)

pub fn has_watcher_with_blocked_thread(&self) -> bool

Returns whether the watched FD has any readiness watcher with a blocked thread watching it.

pub fn remove_file_num_interests(&self, fd_id: FdId, fd_num: i32)

Remove all interes in the given file descriptor, which must refer to the file description that contains self.

Trait Implementations

impl Debug for ReadinessWatched

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

Formats the value using the given formatter.

impl Default for ReadinessWatched

fn default() -> ReadinessWatched

Returns the “default value” for a type.

impl Drop for ReadinessWatched

fn drop(&mut self)

Executes the destructor for this type.

fn pin_drop(self: Pin<&mut Self>)

🔬This is a nightly-only experimental API. (pin_ergonomics)

Execute the destructor for this type, but different to Drop::drop, it requires self to be pinned.

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
