|
||
<p>This crate provides a data structures representing a set of small ordered sets or maps.
|
||
It is implemented as a forest of B+-trees all allocating nodes out of the same pool.</p>
|
||
<p><strong>These are not general purpose data structures that are somehow magically faster that the
|
||
standard library's <code>BTreeSet</code> and <code>BTreeMap</code> types.</strong></p>
|
||
<p>The tradeoffs are different:</p>
|
||
<ul>
|
||
<li>Keys and values are expected to be small and copyable. We optimize for 32-bit types.</li>
|
||
<li>A comparator object is used to compare keys, allowing smaller "context free" keys.</li>
|
||
<li>Empty trees have a very small 32-bit footprint.</li>
|
||
<li>All the trees in a forest can be cleared in constant time.</li>
|
||
</ul>
