Required Methods

fn find<U: ?Sized>(&self, elt: &U) -> Option<usize> where
    Self::Item: PartialEq<U>, 

Linear search for the first occurrence elt in the slice.

Return its index if it is found, or None.

fn rfind<U: ?Sized>(&self, elt: &U) -> Option<usize> where
    Self::Item: PartialEq<U>, 

Linear search for the last occurrence elt in the slice.

Return its index if it is found, or None.
