<h5 id="migrating-to-compare_exchange-and-compare_exchange_weak"><a class="doc-anchor" href="#migrating-to-compare_exchange-and-compare_exchange_weak">§</a>Migrating to <code>compare_exchange</code> and <code>compare_exchange_weak</code></h5>
<p><code>compare_and_swap</code> is equivalent to <code>compare_exchange</code> with the following mapping for
memory orderings:</p>
<div><table><thead><tr><th>Original</th><th>Success</th><th>Failure</th></tr></thead><tbody>
<tr><td>Relaxed</td><td>Relaxed</td><td>Relaxed</td></tr>
<tr><td>Acquire</td><td>Acquire</td><td>Acquire</td></tr>
<tr><td>Release</td><td>Release</td><td>Relaxed</td></tr>
<tr><td>AcqRel</td><td>AcqRel</td><td>Acquire</td></tr>
<tr><td>SeqCst</td><td>SeqCst</td><td>SeqCst</td></tr>
</tbody></table>
</div>
<p><code>compare_and_swap</code> and <code>compare_exchange</code> also differ in their return type. You can use
<code>compare_exchange(...).unwrap_or_else(|x| x)</code> to recover the behavior of <code>compare_and_swap</code>,
but in most cases it is more idiomatic to check whether the return value is <code>Ok</code> or <code>Err</code>
rather than to infer success vs failure based on the value that was read.</p>
<p>During migration, consider whether it makes sense to use <code>compare_exchange_weak</code> instead.
<code>compare_exchange_weak</code> is allowed to fail spuriously even when the comparison succeeds,
which allows the compiler to generate better assembly code when the compare and swap
is used in a loop.</p>

This method is mostly useful for FFI, where the function signature may use

<p>Returning an <code>*mut</code> pointer from a shared reference to this atomic is safe because the
atomic types work with interior mutability. All modifications of an atomic change the value
through a shared reference, and can do so safely as long as they use atomic operations. Any
