Expand description

Types and routines for working with look-around assertions.

This module principally defines two types:

  • Look enumerates all of the assertions supported by this crate.
  • LookSet provides a way to efficiently store a set of Look values.
  • LookMatcher provides routines for checking whether a Look or a LookSet matches at a particular position in a haystack.
