<p>An HIR value is a combination of a <ahref="enum.HirKind.html"title="enum regex_syntax::hir::HirKind"><code>HirKind</code></a> and a set of <ahref="struct.Properties.html"title="struct regex_syntax::hir::Properties"><code>Properties</code></a>.
An <code>HirKind</code> indicates what kind of regular expression it is (a literal,
a repetition, a look-around assertion, etc.), where as a <code>Properties</code>
describes various facts about the regular expression. For example, whether
it matches UTF-8 or if it matches the empty string.</p>
<p>The HIR of a regular expression represents an intermediate step between
its abstract syntax (a structured description of the concrete syntax) and
an actual regex matcher. The purpose of HIR is to make regular expressions
easier to analyze. In particular, the AST is much more complex than the
HIR. For example, while an AST supports arbitrarily nested character
classes, the HIR will flatten all nested classes into a single set. The HIR
will also “compile away” every flag present in the concrete syntax. For
example, users of HIR expressions never need to worry about case folding;
it is handled automatically by the translator (e.g., by translating
<code>(?i:A)</code> to <code>[aA]</code>).</p>
<p>The specific type of an HIR expression can be accessed via its <code>kind</code>
or <code>into_kind</code> methods. This extra level of indirection exists for two
reasons:</p>
<ol>
<li>Construction of an HIR expression <em>must</em> use the constructor methods on
this <code>Hir</code> type instead of building the <code>HirKind</code> values directly. This
permits construction to enforce invariants like “concatenations always
consist of two or more sub-expressions.”</li>
<li>Every HIR expression contains attributes that are defined inductively,
and can be computed cheaply during the construction process. For example,
one such attribute is whether the expression must match at the beginning of
the haystack.</li>
</ol>
<p>In particular, if you have an <code>HirKind</code> value, then there is intentionally
no way to build an <code>Hir</code> value from it. You instead need to do case
analysis on the <code>HirKind</code> value and build the <code>Hir</code> value using its smart
<p>This type defines its own destructor that uses constant stack space and
heap space proportional to the size of the HIR.</p>
<p>Also, an <code>Hir</code>’s <code>fmt::Display</code> implementation prints an HIR as a regular
expression pattern string, and uses constant stack space and heap space
proportional to the size of the <code>Hir</code>. The regex it prints is guaranteed to
be <em>semantically</em> equivalent to the original concrete syntax, but it may
look very different. (And potentially not practically readable by a human.)</p>
<p>An <code>Hir</code>’s <code>fmt::Debug</code> implementation currently does not use constant
stack space. The implementation will also suppress some details (such as
the <code>Properties</code> inlined into every <code>Hir</code> value to make it less noisy).</p>

simplifications. For example, calling <code>Hir::repetition</code> with a repetition
like <code>a{0}</code> will actually return a <code>Hir</code> with a <code>HirKind::Empty</code> kind
since it is equivalent to an empty regex. Another example is calling
<code>Hir::concat(vec![expr])</code>. Instead of getting a <code>HirKind::Concat</code>, you’ll
just get back the original <code>expr</code> since it’s precisely equivalent.</p>
