Struct crossbeam_utils::sync::Unparker [−][src]
pub struct Unparker { /* fields omitted */ }
Expand description
Unparks a thread parked by the associated Parker
.
Implementations
impl Unparker
[src]
impl Unparker
[src]pub fn unpark(&self)
[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]
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]
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) };
