Traits

Haystack

A trait used to interface the haystack types use when matching of capturing against a Regex, including tracking progression and slicing captures.

HaystackOf

This trait is exactly the same as Haystack, except that it simplifies bounds by requiring that Item = I.

HaystackSlice

A trait representing a slice of the underlying haystack for various Haystack types.

IntoHaystack

A trait that is responsible for converting a slice into a stateful Haystack, of type H. The primary intent of this trait is to allow users to avoid creating their own Haystack, instead passing a slice to methods on Regex.

OwnedHaystackable

A trait representing an owned, mutable type that can be converted into a Haystack as required. This allows for Regex methods that replace matches or captures from the original Haystack.
