search in the haystack

return index of the haystack, if it found the needle. Otherwise return None.

Required methods

fn search_in(&self, haystack: &'a str) -> Option<usize>

search self in the haystack.

return index of the haystack, if it found self. Otherwise return None.

fn rsearch_in(&self, haystack: &'a str) -> Option<usize>

reverse search self in the haystack.

return index of the haystack, if it found self. Otherwise return None.

fn len(&self) -> usize

return the length of self

Provided methods

fn is_empty(&self) -> bool

true if a length of 0.

fn includes_in(&self, haystack: &'a str) -> bool

includes self in the haystack.

returns true if the given pattern matches a sub-slice of this string slice. returns false if it does not.
