<p>This can be implemented for custom data types to allow them to be decoded
with <code>Decoder</code> implementations. Most of Rust's built-in or standard data
types (like <code>i32</code> and <code>Vec<T></code>) have <code>Decodable</code> implementations provided by
this module.</p>
<p>Note that, in general, you should let the compiler implement this for you by
using the <code>derive(RustcDecodable)</code> attribute.</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>)
