<p>The HIR of a regular expression represents an intermediate step between its
abstract syntax (a structured description of the concrete syntax) and
compiled byte codes. 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 &quot;compile away&quot; 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>If the HIR was produced by a translator that disallows invalid UTF-8, then
the HIR is guaranteed to match UTF-8 exclusively.</p>
<p>This type defines its own destructor that uses constant stack space and
heap space proportional to the size of the HIR.</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 &quot;concatenations
always consist of two or more sub-expressions.&quot;</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 text.</li>
</ol>
<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>.</p>
