<p>It is not expected for consumers of this crate to need to use this type
unless they are implementing their own DFA. And even then, it’s not
required: implementors may use other techniques to handle haystack units.</p>
<p>Typically, a single unit of haystack for a DFA would be a single byte.
However, for the DFAs in this crate, matches are delayed by a single byte
in order to handle look-ahead assertions (<code>\b</code>, <code>$</code> and <code>\z</code>). Thus, once
we have consumed the haystack, we must run the DFA through one additional
transition using a unit that indicates the haystack has ended.</p>
<p>There is no way to represent a sentinel with a <code>u8</code> since all possible
values <em>may</em> be valid haystack units to a DFA, therefore this type
explicitly adds room for a sentinel value.</p>
<p>The sentinel EOI value is always its own equivalence class and is
ultimately represented by adding 1 to the maximum equivalence class value.
So for example, the regex <code>^[a-z]+$</code> might be split into the following
<p>Where EOI is the special sentinel value that is always in its own
singleton equivalence class.</p>

in-memory representation is to collapse its transitions to a set of
