pub trait Mutable {

Required Methods

fn set(&mut self, keys: &[Self::Key], new: &Self::Item)

Set the new Value at the path identified by keys.

Intermediate container values (like HashMaps, Arrays) must be created until the last Key in keys can be modified or inserted with new.

Remove the value located at the path identified by keys.

If the value does not exist, just return. Intermediate container values must not be created.
