<p>When executing a search, there are a few parameters one might want to
configure:</p>
<ul>
<li>The haystack to search, provided to the <a href="struct.Input.html#method.new" title="associated function aho_corasick::Input::new"><code>Input::new</code></a> constructor. This
is the only required parameter.</li>
<li>The span <em>within</em> the haystack to limit a search to. (The default
is the entire haystack.) This is configured via <a href="struct.Input.html#method.span" title="method aho_corasick::Input::span"><code>Input::span</code></a> or
<a href="struct.Input.html#method.range" title="method aho_corasick::Input::range"><code>Input::range</code></a>.</li>
<li>Whether to run an unanchored (matches can occur anywhere after the
start of the search) or anchored (matches can only occur beginning at
the start of the search) search. Unanchored search is the default. This is
configured via <a href="struct.Input.html#method.anchored" title="method aho_corasick::Input::anchored"><code>Input::anchored</code></a>.</li>
<li>Whether to quit the search as soon as a match has been found, regardless
of the <a href="enum.MatchKind.html" title="enum aho_corasick::MatchKind"><code>MatchKind</code></a> that the searcher was built with. This is configured
via <a href="struct.Input.html#method.earliest" title="method aho_corasick::Input::earliest"><code>Input::earliest</code></a>.</li>
</ul>
<p>For most cases, the defaults for all optional parameters are appropriate.
The utility of this type is that it keeps the default or common case simple
while permitting tweaking parameters in more niche use cases while reusing
the same search APIs.</p>
<h2 id="valid-bounds-and-search-termination"><a class="doc-anchor" href="#valid-bounds-and-search-termination">§</a>Valid bounds and search termination</h2>
<p>An <code>Input</code> permits setting the bounds of a search via either
<a href="struct.Input.html#method.span" title="method aho_corasick::Input::span"><code>Input::span</code></a> or <a href="struct.Input.html#method.range" title="method aho_corasick::Input::range"><code>Input::range</code></a>. The bounds set must be valid, or
else a panic will occur. Bounds are valid if and only if:</p>
<ul>
<li>The bounds represent a valid range into the input’s haystack.</li>
<li><strong>or</strong> the end bound is a valid ending bound for the haystack <em>and</em>
the start bound is exactly one greater than the end bound.</li>
</ul>
<p>In the latter case, <a href="struct.Input.html#method.is_done" title="method aho_corasick::Input::is_done"><code>Input::is_done</code></a> will return true and indicates any
search receiving such an input should immediately return with no match.</p>
<p>Other than representing “search is complete,” the <code>Input::span</code> and
<code>Input::range</code> APIs are never necessary. Instead, callers can slice the
haystack instead, e.g., with <code>&amp;haystack[start..end]</code>. With that said, they
can be more convenient than slicing because the match positions reported
when using <code>Input::span</code> or <code>Input::range</code> are in terms of the original
haystack. If you instead use <code>&amp;haystack[start..end]</code>, then you’ll need to
add <code>start</code> to any match position returned in order for it to be a correct
index into <code>haystack</code>.</p>
<h2 id="example-str-and-u8-automatically-convert-to-an-input"><a class="doc-anchor" href="#example-str-and-u8-automatically-convert-to-an-input">§</a>Example: <code>&amp;str</code> and <code>&amp;[u8]</code> automatically convert to an <code>Input</code></h2>
<p>There is a <code>From&lt;&amp;T&gt; for Input</code> implementation for all <code>T: AsRef&lt;[u8]&gt;</code>.
Additionally, the <a href="struct.AhoCorasick.html" title="struct aho_corasick::AhoCorasick"><code>AhoCorasick</code></a> search APIs accept
a <code>Into&lt;Input&gt;</code>. These two things combined together mean you can provide
things like <code>&amp;str</code> and <code>&amp;[u8]</code> to search APIs when the defaults are
suitable, but also an <code>Input</code> when they’re not. For example:</p>

<p>When running a non-overlapping search, an “earliest” search will
return the match location as early as possible. For example, given
the patterns <code>abc</code> and <code>b</code>, and a haystack of <code>abc</code>, a normal
leftmost-first search will return <code>abc</code> as a match. But an “earliest”
search will return as soon as it is known that a match occurs, which
happens once <code>b</code> is seen.</p>
<p>Note that when using <a href="enum.MatchKind.html#variant.Standard" title="variant aho_corasick::MatchKind::Standard"><code>MatchKind::Standard</code></a>, the “earliest” option
has no effect since standard semantics are already “earliest.” Note
also that this has no effect in overlapping searches, since overlapping
searches also use standard semantics and report all possible matches.</p>
<p>This is disabled by default.</p>
