|

|
|
<p>This parser takes as input a regular expression pattern string (the
|
|||
|
|
"concrete syntax") and returns a high-level intermediate representation
|
|||
|
|
(the HIR) suitable for most types of analysis. In particular, this parser
|
|||
|
|
hides the intermediate state of producing an AST (the "abstract syntax").
|
|||
|
|
The AST is itself far more complex than the HIR, so this parser serves as a
|
|||
|
|
convenience for never having to deal with it at all.</p>
|
|||
|
|
<p>If callers have more fine grained use cases that need an AST, then please
|
|||
|
|
see the <a href="ast/parse/index.html"><code>ast::parse</code></a> module.</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>)
|
|||
|
|
