Implementations

impl Search

pub fn search( &mut self, list: &[Utf32String], direction: Direction, ) -> Option<usize>

Searches for pattern in the list and the given direction. Returns the index of the first match.

Examples

let mut search = Search::default();
search.pattern = String::from("ap");

let list = ["apple", "pineapple", "clementine"]
    .iter()
    .map(|s| Utf32String::from(*s))
    .collect::<Vec<_>>();

let idx = search.search(&list, Direction::Forward);
assert_eq!(idx, Some(0));

let idx = search.search(&list, Direction::Backward);
assert_eq!(idx, Some(1));

search.start_idx = Some(0);
let idx = search.search(&list, Direction::Forward);
assert_eq!(idx, Some(1));

pub fn next_match(&mut self) -> Option<&usize>

Returns the index of the first match after start_idx or the first match if it is None.

pub fn previous_match(&mut self) -> Option<&usize>

Returns the index of the first match before start_idx or the last match if it is None.

pub fn no_match(&self) -> bool

Returns true if the pattern isn’t empty and there isn’t a match.

Trait Implementations

impl Default for Search

fn default() -> Search
