Struct crossbeam_utils::sync::Unparker[][src]

pub struct Unparker { /* fields omitted */ }

Unparks a thread parked by the associated Parker.

Implementations

impl Unparker[src]

pub fn unpark(&self)[src]

Atomically makes the token available if it is not already.

This method will wake up the thread blocked on park or park_timeout, if there is any.

Examples

use std::thread;
use std::time::Duration;
use crossbeam_utils::sync::Parker;

let p = Parker::new();
let u = p.unparker().clone();

thread::spawn(move || {
    thread::sleep(Duration::from_millis(500));
    u.unpark();
});

// Wakes up when `u.unpark()` provides the token.
p.park();

pub fn into_raw(this: Unparker) -> *const ()[src]

Converts an Unparker into a raw pointer.

Examples

use crossbeam_utils::sync::{Parker, Unparker};

let p = Parker::new();
let u = p.unparker().clone();
let raw = Unparker::into_raw(u);

pub unsafe fn from_raw(ptr: *const ()) -> Unparker[src]

Converts a raw pointer into an Unparker.

Safety

This method is safe to use only with pointers returned by Unparker::into_raw.

Examples

use crossbeam_utils::sync::{Parker, Unparker};

let p = Parker::new();
let u = p.unparker().clone();

let raw = Unparker::into_raw(u);
let u = unsafe { Unparker::from_raw(raw) };
