A string pattern.

A Pattern<'a> expresses that the implementing type can be used as a string pattern for searching in a &'a str.

For example, both 'a' and "aa" are patterns that would match at index 1 in the string "baaaab".

The trait itself acts as a builder for an associatedSearcher type, which does the actual work of finding occurrences of the pattern in a string.

Associated searcher for this pattern

fn [into_searcher](#tymethod.into%5Fsearcher)(self, haystack: &'a [str](../../primitive.str.html)) -> Self::[Searcher](../../../std/str/pattern/trait.Pattern.html#associatedtype.Searcher "type std::str::pattern::Pattern::Searcher")

Constructs the associated searcher fromself and the haystack to search in.
