pub struct Unparker { /* private fields */ }
Expand description
Unparks a thread parked by the associated Parker
.
Implementations§
source§impl Unparker
impl Unparker
sourcepub fn unpark(&self)
pub fn unpark(&self)
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();
sourcepub fn into_raw(this: Unparker) -> *const ()
pub fn into_raw(this: Unparker) -> *const ()
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);
sourcepub unsafe fn from_raw(ptr: *const ()) -> Unparker
pub unsafe fn from_raw(ptr: *const ()) -> Unparker
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) };
