<span class='doccomment'>//! Atomic types</span>
<span class='doccomment'>//!</span>
<span class='doccomment'>//! Atomic types provide primitive shared-memory communication between</span>
<span class='doccomment'>//! threads, and are the building blocks of other concurrent</span>
<span class='doccomment'>//! types.</span>
<span class='doccomment'>//!</span>
<span class='doccomment'>//! This module defines atomic versions of a select number of primitive</span>
<span class='doccomment'>//! types, including `AtomicBool`, `AtomicIsize`, and `AtomicUsize`.</span>
<span class='doccomment'>//! Atomic types present operations that, when used correctly, synchronize</span>
<span class='doccomment'>//! updates between threads.</span>
<span class='doccomment'>//!</span>
<span class='doccomment'>//! Each method takes an `Ordering` which represents the strength of</span>
<span class='doccomment'>//! the memory barrier for that operation. These orderings are the</span>
<span class='doccomment'>//! same as [LLVM atomic orderings][1].</span>
<span class='doccomment'>//!</span>
<span class='doccomment'>//! [1]: http://llvm.org/docs/LangRef.html#memory-model-for-concurrent-operations</span>
<span class='doccomment'>//!</span>
<span class='doccomment'>//! Atomic variables are safe to share between threads (they implement `Sync`)</span>
<span class='doccomment'>//! but they do not themselves provide the mechanism for sharing. The most</span>
<span class='doccomment'>//! common way to share an atomic variable is to put it into an `Arc` (an</span>
<span class='doccomment'>//! atomically-reference-counted shared pointer).</span>
<span class='doccomment'>//!</span>
<span class='doccomment'>//! Most atomic types may be stored in static variables, initialized using</span>
<span class='doccomment'>//! the provided static initializers like `INIT_ATOMIC_BOOL`. Atomic statics</span>
<span class='doccomment'>//! are often used for lazy global initialization.</span>
<span class='doccomment'>//!</span>
<span class='doccomment'>//!</span>
<span class='doccomment'>//! # Examples</span>
<span class='doccomment'>//!</span>
<span class='doccomment'>//! A simple spinlock:</span>
<span class='doccomment'>//!</span>
<span class='doccomment'>//! ```</span>
<span class='doccomment'>//! use std::sync::Arc;</span>
<span class='doccomment'>//! use std::sync::atomic::{AtomicUsize, Ordering};</span>
<span class='doccomment'>//! use std::thread;</span>
<span class='doccomment'>//!</span>
<span class='doccomment'>//! fn main() {</span>
<span class='doccomment'>//!     let spinlock = Arc::new(AtomicUsize::new(1));</span>
<span class='doccomment'>//!</span>
<span class='doccomment'>//!     let spinlock_clone = spinlock.clone();</span>
<span class='doccomment'>//!     thread::spawn(move|| {</span>
<span class='doccomment'>//!         spinlock_clone.store(0, Ordering::SeqCst);</span>
<span class='doccomment'>//!     });</span>
<span class='doccomment'>//!</span>
<span class='doccomment'>//!     // Wait for the other task to release the lock</span>
<span class='doccomment'>//!     while spinlock.load(Ordering::SeqCst) != 0 {}</span>
<span class='doccomment'>//! }</span>
<span class='doccomment'>//! ```</span>
<span class='doccomment'>//!</span>
<span class='doccomment'>//! Keep a global count of live tasks:</span>
<span class='doccomment'>//!</span>
<span class='doccomment'>//! ```</span>
<span class='doccomment'>//! use std::sync::atomic::{AtomicUsize, Ordering, ATOMIC_USIZE_INIT};</span>
<span class='doccomment'>//!</span>
<span class='doccomment'>//! static GLOBAL_TASK_COUNT: AtomicUsize = ATOMIC_USIZE_INIT;</span>
<span class='doccomment'>//!</span>
<span class='doccomment'>//! let old_task_count = GLOBAL_TASK_COUNT.fetch_add(1, Ordering::SeqCst);</span>
<span class='doccomment'>//! println!(&quot;live tasks: {}&quot;, old_task_count + 1);</span>
