|
||
<p>This crate is an early work in progress. The focus for the moment is
|
||
concurrency:</p>
|
||
<ul>
|
||
<li>
|
||
<p><strong>Non-blocking data structures</strong>. These data structures allow for high
|
||
performance, highly-concurrent access, much superior to wrapping with a
|
||
<code>Mutex</code>. Ultimately the goal is to include stacks, queues, deques, bags,
|
||
sets and maps. These live in the <code>sync</code> module.</p>
|
||
</li>
|
||
<li>
|
||
<p><strong>Memory management</strong>. Because non-blocking data structures avoid global
|
||
synchronization, it is not easy to tell when internal data can be safely
|
||
freed. The <code>mem</code> module provides generic, easy to use, and high-performance
|
||
APIs for managing memory in these cases. These live in the <code>mem</code> module.</p>
|
||
</li>
|
||
<li>
|
||
<p><strong>Synchronization</strong>. The standard library provides a few synchronization
|
||
primitives (locks, barriers, etc) but this crate seeks to expand that set
|
||
to include more advanced/niche primitives, as well as userspace
|
||
alternatives. These live in the <code>sync</code> module.</p>
|
||
</li>
|
||
<li>
|
||
<p><strong>Scoped thread API</strong>. Finally, the crate provides a "scoped" thread API,
|
||
making it possible to spawn threads that share stack data with their
|
||
parents. This functionality is exported at the top-level.</p>
|
||
</li>
|
||
</ul>

<h2>Search Tricks</h2>
|
||
|
||
<p>
|
||
Prefix searches with a type followed by a colon (e.g.
|
||
<code>fn:</code>) to restrict the search to a given type.
|
||
</p>
|
||
|
||
<p>
|
||
Accepted types are: <code>fn</code>, <code>mod</code>,
|
||
<code>struct</code>, <code>enum</code>,
|
||
<code>trait</code>, <code>type</code>, <code>macro</code>,
|
||
and <code>const</code>.
|
||
</p>
|
||
|
||
<p>
|
||
Search functions by type signature (e.g.
|
||
<code>vec -> usize</code> or <code>* -> vec</code>)
