<p>An assertion matches at a position between characters in a haystack.
Namely, it does not actually “consume” any input as most parts of a regular
expression do. Assertions are a way of stating that some property must be
true at a particular point during matching.</p>
<p>For example, <code>(?m)^[a-z]+$</code> is a pattern that:</p>
<ul>
<li>Scans the haystack for a position at which <code>(?m:^)</code> is satisfied. That
occurs at either the beginning of the haystack, or immediately following
a <code>\n</code> character.</li>
<li>Looks for one or more occurrences of <code>[a-z]</code>.</li>
<li>Once <code>[a-z]+</code> has matched as much as it can, an overall match is only
reported when <code>[a-z]+</code> stops just before a <code>\n</code>.</li>
</ul>
<p>So in this case, <code>abc</code> and <code>\nabc\n</code> match, but <code>\nabc1\n</code> does not.</p>
<p>Assertions are also called “look-around,” “look-behind” and “look-ahead.”
Specifically, some assertions are look-behind (like <code>^</code>), other assertions
are look-ahead (like <code>$</code>) and yet other assertions are both look-ahead and
look-behind (like <code>\b</code>).</p>
<h2id="assertions-in-an-nfa"><ahref="#assertions-in-an-nfa">Assertions in an NFA</a></h2>
<p>An assertion in a <ahref="../../nfa/thompson/struct.NFA.html"title="struct regex_automata::nfa::thompson::NFA"><code>thompson::NFA</code></a> can be
thought of as a conditional epsilon transition. That is, a matching engine
like the <ahref="../../nfa/thompson/pikevm/struct.PikeVM.html"title="struct regex_automata::nfa::thompson::pikevm::PikeVM"><code>PikeVM</code></a> only permits
moving through conditional epsilon transitions when their condition
is satisfied at whatever position the <code>PikeVM</code> is currently at in the
haystack.</p>
<p>How assertions are handled in a <code>DFA</code> is trickier, since a DFA does not
have epsilon transitions at all. In this case, they are compiled into the
automaton itself, at the expense of more states than what would be required
without an assertion.</p>
