<p>In theory, it can help to conceptualize an <code>NFA</code> as a graph consisting of
<code>State</code>s. Each <code>State</code> contains its complete set of outgoing transitions.</p>
<p>In practice, it can help to conceptualize an <code>NFA</code> as a sequence of
instructions for a virtual machine. Each <code>State</code> says what to do and where
to go next.</p>
<p>Strictly speaking, the practical interpretation is the most correct one,
because of the <ahref="enum.State.html#variant.Capture"title="variant regex_automata::nfa::thompson::State::Capture"><code>Capture</code></a> state. Namely, a <code>Capture</code>
state always forwards execution to another state unconditionally. Its only
purpose is to cause a side effect: the recording of the current input
position at a particular location in memory. In this sense, an <code>NFA</code>
has more power than a theoretical non-deterministic finite automaton.</p>
<p>For most uses of this crate, it is likely that one may never even need to
be aware of this type at all. The main use cases for looking at <code>State</code>s
directly are if you need to write your own search implementation or if you
need to do some kind of analysis on the NFA.</p>

epsilon transitions (via <ahref="enum.State.html#variant.Union"title="variant regex_automata::nfa::thompson::State::Union"><code>Union</code></a> states), and thus
