literal	Provides routines for extracting literal prefixes and suffixes from an `Hir`.
print	This module provides a regular expression printer for `Hir`.
translate	Defines a translator that converts an `Ast` to an `Hir`.
visitor

ClassBytes	A set of characters represented by arbitrary bytes (where one byte corresponds to one character).
ClassBytesIter	An iterator over all ranges in a byte character class.
ClassBytesRange	A single range of characters represented by arbitrary bytes.
ClassUnicode	A set of characters represented by Unicode scalar values.
ClassUnicodeIter	An iterator over all ranges in a Unicode character class.
ClassUnicodeRange	A single range of characters represented by Unicode scalar values.
Error	An error that can occur while translating an `Ast` to a `Hir`.
Group	The high-level intermediate representation for a group.
Hir	A high-level intermediate representation (HIR) for a regular expression.
HirInfo	A type that documents various attributes of an HIR expression.
Repetition	The high-level intermediate representation of a repetition operator.

Anchor	The high-level intermediate representation for an anchor assertion.
Class	The high-level intermediate representation of a character class.
ErrorKind	The type of an error that occurred while building an `Hir`.
GroupKind	The kind of group.
HirKind	The kind of an arbitrary `Hir` expression.
Literal	The high-level intermediate representation of a literal.
RepetitionKind	The kind of a repetition operator.
RepetitionRange	The kind of a counted repetition operator.
WordBoundary	The high-level intermediate representation for a word-boundary assertion.

A trait for visiting the high-level IR (HIR) in depth first order.

Executes an implementation of Visitor in constant stack space.
