| <p>Here we have some more general topics that might be good to know that just don’t fit to the |
| crate level intro.</p> |
| <p>Also, there were some previous blog posts about the crate which you might find interesting.</p> |
| <h2 id="atomic-orderings"><a href="#atomic-orderings">Atomic orderings</a></h2> |
| <p>Each operation on the <a href="../struct.ArcSwapAny.html"><code>ArcSwapAny</code></a> with <a href="../strategy/type.DefaultStrategy.html"><code>DefaultStrategy</code></a> type callable concurrently (eg. |
| <a href="../struct.ArcSwapAny.html#method.load"><code>load</code></a>, but not <a href="../struct.ArcSwapAny.html#method.into_inner"><code>into_inner</code></a>) contains at least one <a href="std::sync::atomic::Ordering::SeqCst"><code>SeqCst</code></a> atomic read-write operation, |
| therefore even operations on different instances have a defined global order of operations.</p> |
| <h2 id="features"><a href="#features">Features</a></h2> |
| <p>The <code>weak</code> feature adds the ability to use arc-swap with the <a href="std::sync::Weak"><code>Weak</code></a> pointer too, |
| through the <a href="crate::ArcSwapWeak"><code>ArcSwapWeak</code></a> type. The needed std support is stabilized in rust version 1.45 (as |
| of now in beta).</p> |
| <p>The <code>experimental-strategies</code> enables few more strategies that can be used. Note that these |
| <strong>are not</strong> part of the API stability guarantees and they may be changed, renamed or removed at |
| any time.</p> |
| <h2 id="minimal-compiler-version"><a href="#minimal-compiler-version">Minimal compiler version</a></h2> |
| <p>The <code>1</code> versions will compile on all compilers supporting the 2018 edition. Note that this |
| applies only if no additional feature flags are enabled and does not apply to compiling or |
| running tests.</p> |
