<p>This API provided by this sub-module is close in spirit to the API
|
||
provided by
|
||
<a href="http://doc.rust-lang.org/stable/std/collections/struct.BTreeSet.html"><code>std::collections::BTreeSet</code></a>.
|
||
The principle difference, as with everything else in this crate, is that
|
||
operations are performed on streams of byte strings instead of generic
|
||
iterators. Another difference is that most of the set operations (union,
|
||
intersection, difference and symmetric difference) work on multiple sets at
|
||
the same time, instead of two.</p>

|
||
<p><code>Set</code> is a read only interface to pre-constructed sets. <code>SetBuilder</code> is
|
||
used to create new sets. (Once a set is created, it can never be modified.)
|
||
<code>Stream</code> is a stream of values that originated from a set (analogous to an
|
||
iterator). <code>StreamBuilder</code> builds range queries. <code>OpBuilder</code> collects a set
|
||
of streams and executes set operations like <code>union</code> or <code>intersection</code> on
|
||
them. The rest of the types are streams for set operations.</p>

<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>)
