<div class='docblock'><p>A macro for defining <code>#[cfg]</code> if-else statements.</p>
|
||
<p>The macro provided by this crate, <code>cfg_if</code>, is similar to the <code>if/elif</code> C
|
||
preprocessor macro by allowing definition of a cascade of <code>#[cfg]</code> cases,
|
||
emitting the implementation which matches first.</p>
|
||
<p>This allows you to conveniently provide a long list <code>#[cfg]</code>'d blocks of code
|

without having to rewrite each clause multiple times.</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>)

||
