<p>This function will visit every node in the given <code>Hir</code> while calling
|
|
appropriate methods provided by the <a href="trait.Visitor.html" title="trait regex_syntax::hir::Visitor"><code>Visitor</code></a> trait.</p>
|
|
<p>The primary use case for this method is when one wants to perform case
|
|
analysis over an <code>Hir</code> without using a stack size proportional to the depth
|
|
of the <code>Hir</code>. Namely, this method will instead use constant stack space,
|
|
but will use heap space proportional to the size of the <code>Hir</code>. This may be
|
|
desirable in cases where the size of <code>Hir</code> is proportional to end user
|
|
input.</p>
|
|
<p>If the visitor returns an error at any point, then visiting is stopped and
|
|
the error is returned.</p>
