|

<h2 id="order"><a class="doc-anchor" href="#order">§</a>Order</h2>
|
||
<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
|
||
<a href="struct.IndexMap.html#method.remove" title="method indexmap::map::IndexMap::remove"><code>.remove()</code></a> or <a href="struct.IndexMap.html#method.swap_remove" title="method indexmap::map::IndexMap::swap_remove"><code>.swap_remove()</code></a> methods.
|
||
Methods such as <a href="struct.IndexMap.html#method.sort_by" title="method indexmap::map::IndexMap::sort_by"><code>.sort_by()</code></a> of
|
||
course result in a new order, depending on the sorting order.</p>
|
||
<h2 id="indices"><a class="doc-anchor" href="#indices">§</a>Indices</h2>
|
||
<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>
