Module regex_syntax::hir

Defines a high-level intermediate representation for regular expressions.

Modules

• 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.

Structs

• CaseFoldError
  An error that occurs when Unicode-aware simple case folding fails.
• 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.
• Repetition
  The high-level intermediate representation of a repetition operator.

Enums

• 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.

Traits

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

Functions

• visit
  Executes an implementation of Visitor in constant stack space.
