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 associated
Searcher type, which does the actual work of finding
occurrences of the pattern in a string.

Associated searcher for this pattern
Required Methods
fn into_searcher(self, haystack: &'a str) -> Self::Searcher
🔬 This is a nightly-only experimental API. (pattern)
API not fully fleshed out and ready to be stabilized
Constructs the associated searcher from
self and the haystack to search in.
Provided Methods
fn is_contained_in(self, haystack: &'a str) -> bool
🔬 This is a nightly-only experimental API. (pattern)
API not fully fleshed out and ready to be stabilized
Checks whether the pattern matches anywhere in the haystack
fn is_prefix_of(self, haystack: &'a str) -> bool
🔬 This is a nightly-only experimental API. (pattern)
API not fully fleshed out and ready to be stabilized
Checks whether the pattern matches at the front of the haystack
fn is_suffix_of(self, haystack: &'a str) -> bool where Self::Searcher: ReverseSearcher<'a>
🔬 This is a nightly-only experimental API. (pattern)
API not fully fleshed out and ready to be stabilized
Checks whether the pattern matches at the back of the haystack
