|
||
<p>A <code>Set</code> is constructed with the <code>SetBuilder</code> type. Alternatively, a <code>Set</code>
|
||
can be constructed in memory from a lexicographically ordered iterator
|
||
of byte strings (<code>Set::from_iter</code>).</p>
|
||
<p>A key feature of <code>Set</code> is that it can be serialized to disk compactly. Its
|
||
underlying representation is built such that the <code>Set</code> can be memory mapped
|
||
(<code>Set::from_path</code>) and searched without necessarily loading the entire
|
||
set into memory.</p>
|
||
<p>It supports most common operations associated with sets, such as
|
||
membership, union, intersection, subset/superset, etc. It also supports
|
||
range queries and automata based searches (e.g. a regular expression).</p>
|
||
<p>Sets are represented by a finite state transducer where output values are
|
||
always zero. As such, sets have the following invariants:</p>
|
||
<ol>
|
||
<li>Once constructed, a <code>Set</code> can never be modified.</li>
|
||
<li>Sets must be constructed with lexicographically ordered byte sequences.</li>
|
||
</ol>
