<div class='docblock'><p>Operations on raw finite state transducers.</p>
|
||
<p>This sub-module exposes the guts of a finite state transducer. Many parts of
|
||
it, such as construction and traversal, are mirrored in the <code>set</code> and <code>map</code>
|
||
sub-modules. Other parts of it, such as direct access to nodes and transitions
|
||
in the transducer, do not have any analog.</p>

||
<h1 id="overview-of-types" class="section-header"><a href="#overview-of-types">Overview of types</a></h1>
|
||
<p><code>Fst</code> is a read only interface to pre-constructed finite state transducers.
|
||
<code>Node</code> is a read only interface to a single node in a transducer. <code>Builder</code> is
|
||
used to create new finite state transducers. (Once a transducer is created, it
|
||
can never be modified.) <code>Stream</code> is a stream of all inputs and outputs in a
|
||
transducer. <code>StreamBuilder</code> builds range queries. <code>OpBuilder</code> collects streams
|
||
and executes set operations like <code>union</code> or <code>intersection</code> on them with the
|
||
option of specifying a merge strategy for output values.</p>
|
||
<p>Most of the rest of the types are streams from 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>)
