Trait IndexedMut

pub trait IndexedMut<T> {
    type Element: ?Sized;

    // Required method
    fn get_mut(&mut self, i: T) -> Option<&mut Self::Element>;
}

Gets a ref to a value based on n index, returns None if the current Value isn’t an Array or doesn’t contain the index it was asked for.

Implementations on Foreign Types
