Unable to modify a key that is of type KeyMut

[johnsonw]

Hello, I am in the process of mutably traversing a TOML file using toml_edit. When I come across a key that I need to change I am not able to change the key's value even though the key is of type KeyMut. The key cannot be changed because the property is not public and I can't seem to find any methods that allow me to mutate its value. As an example, let's say that I have the following in my toml file:

[host1.network_interface.eth0]
name = "name"
...

In this example, I want to change the eth0 key to enp0s2. Is it possible to do this using the toml_edit crate?

If you look at HashMap, you can't edit keys in-place. You have to remove the entry and insert a new one. The same for toml_edit. The role of KeyMut is for changing the aspects of a key that are independent of its lookup-properties.

Fair enough. Thank you for the clarification 👍
