Trait Indexing 

pub trait Indexing<T, E> {

fn get_mut_at<'a>(&self, root: &'a mut T, idx: usize) -> &'a mut E

fn set_at(&self, root: &mut T, idx: usize, value: E)

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
