pub struct MatchIndices<'a> {
// some fields omitted
}An iterator over the start and end indices of the matches of a substring within a larger string
impl<'a> Iterator for MatchIndices<'a>type Item = (usize, usize)fn next(&mut self) -> Option<(usize, usize)>fn size_hint(&self) -> (usize, Option<usize>)impl<'a> Clone for MatchIndices<'a>fn clone(&self) -> MatchIndices<'a>fn clone_from(&mut self, &MatchIndices<'a>)
Prefix searches with a type followed by a colon (e.g.
fn:) to restrict the search to a given type.
Accepted types are: fn, mod,
struct, enum,
trait, typedef (or
tdef).
