|
|||
|
|
of the hash values of the keys.</p>
|
|||
|
|
<p>The interface is closely compatible with the standard <code>HashMap</code>, but also
|
|||
|
|
has additional features.</p>
|
|||
|
|
<h1 id="order" class="section-header"><a href="#order">Order</a></h1>
|
|||
|
|
<p>The key-value pairs have a consistent order that is determined by
|
|||
|
|
the sequence of insertion and removal calls on the map. The order does
|
|||
|
|
not depend on the keys or the hash function at all.</p>
|
|||
|
|
<p>All iterators traverse the map in <em>the order</em>.</p>
|
|||
|
|
<p>The insertion order is preserved, with <strong>notable exceptions</strong> like the
|
|||
|
|
<code>.remove()</code> or <code>.swap_remove()</code> methods. Methods such as <code>.sort_by()</code> of
|
|||
|
|
course result in a new order, depending on the sorting order.</p>
|
|||
|
|
<h1 id="indices" class="section-header"><a href="#indices">Indices</a></h1>
|
|||
|
|
<p>The key-value pairs are indexed in a compact range without holes in the
|
|||
|
|
range <code>0..self.len()</code>. For example, the method <code>.get_full</code> looks up the
|
|||
|
|
index for a key, and the method <code>.get_index</code> looks up the key-value pair by
|
|||
|
|
index.</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>)
|
|||
|
|
