<h2 id="overview"><a href="#overview">Overview</a></h2>
<p>This list represents the principle types in this module and briefly describes
when you might want to use them.</p>
<ul>
<li><a href="../../struct.PatternID.html" title="struct regex_automata::PatternID"><code>PatternID</code></a> - A type that represents the identifier of a regex pattern.
This is probably the most widely used type in this module (which is why it’s
also re-exported in the crate root).</li>
<li><a href="struct.StateID.html" title="struct regex_automata::util::primitives::StateID"><code>StateID</code></a> - A type the represents the identifier of a finite automaton
state. This is used for both NFAs and DFAs, with the notable exception of
the hybrid NFA/DFA. (The hybrid NFA/DFA uses a special purpose “lazy” state
identifier.)</li>
<li><a href="struct.SmallIndex.html" title="struct regex_automata::util::primitives::SmallIndex"><code>SmallIndex</code></a> - The internal representation of both a <code>PatternID</code> and a
<code>StateID</code>. Its purpose is to serve as a type that can index memory without
being as big as a <code>usize</code> on 64-bit targets. The main idea behind this type
is that there are many things in regex engines that will, in practice, never
overflow a 32-bit integer. (For example, like the number of patterns in a regex
or the number of states in an NFA.) Thus, a <code>SmallIndex</code> can be used to index
memory without peppering <code>as</code> casts everywhere. Moreover, it forces callers
to handle errors in the case where, somehow, the value would otherwise overflow
either a 32-bit integer or a <code>usize</code> (e.g., on 16-bit targets).</li>
<li><a href="struct.NonMaxUsize.html" title="struct regex_automata::util::primitives::NonMaxUsize"><code>NonMaxUsize</code></a> - Represents a <code>usize</code> that cannot be <code>usize::MAX</code>. As a
result, <code>Option&lt;NonMaxUsize&gt;</code> has the same size in memory as a <code>usize</code>. This
useful, for example, when representing the offsets of submatches since it
reduces memory usage by a factor of 2. It is a legal optimization since Rust
guarantees that slices never have a length that exceeds <code>isize::MAX</code>.</li>
</ul>
