|
|||
|
|
hash values.</p>
|
|||
|
|
<p>The interface is closely compatible with the standard
|
|||
|
|
<a href="https://doc.rust-lang.org/1.76.0/std/collections/hash/set/struct.HashSet.html" title="struct std::collections::hash::set::HashSet"><code>HashSet</code></a>,
|
|||
|
|
but also has additional features.</p>
|
|||
|
|
<h2 id="order"><a href="#order">Order</a></h2>
|
|||
|
|
<p>The values have a consistent order that is determined by the sequence of
|
|||
|
|
insertion and removal calls on the set. The order does not depend on the
|
|||
|
|
values or the hash function at all. Note that insertion order and value
|
|||
|
|
are not affected if a re-insertion is attempted once an element is
|
|||
|
|
already present.</p>
|
|||
|
|
<p>All iterators traverse the set <em>in order</em>. Set operation iterators like
|
|||
|
|
<a href="struct.IndexSet.html#method.union" title="method indexmap::set::IndexSet::union"><code>IndexSet::union</code></a> produce a concatenated order, as do their matching “bitwise”
|
|||
|
|
operators. See their documentation for specifics.</p>
|
|||
|
|
<p>The insertion order is preserved, with <strong>notable exceptions</strong> like the
|
|||
|
|
<a href="struct.IndexSet.html#method.remove" title="method indexmap::set::IndexSet::remove"><code>.remove()</code></a> or <a href="struct.IndexSet.html#method.swap_remove" title="method indexmap::set::IndexSet::swap_remove"><code>.swap_remove()</code></a> methods.
|
|||
|
|
Methods such as <a href="struct.IndexSet.html#method.sort_by" title="method indexmap::set::IndexSet::sort_by"><code>.sort_by()</code></a> of
|
|||
|
|
course result in a new order, depending on the sorting order.</p>
|
|||
|
|
<h2 id="indices"><a href="#indices">Indices</a></h2>
|
|||
|
|
<p>The values 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 value, and the method <code>.get_index</code> looks up the value by index.</p>
|
|||
|
|
<h2 id="complexity"><a href="#complexity">Complexity</a></h2>
|
|||
|
|
<p>Internally, <code>IndexSet<T, S></code> just holds an <a href="../map/struct.IndexMap.html" title="struct indexmap::map::IndexMap"><code>IndexMap<T, (), S></code></a>. Thus the complexity
|
|||
|
|
of the two are the same for most methods.</p>
