Is this possible? Or is there an easy way to extend slotmap or write a new type of slotmap that supports this?

let mut thing = slotmap::SlotMap::new();
let a = thing.insert("hello");
let b = thing.insert("hello");
assert_eq!(a, b);

Hi, this is commonly known as "string interning", if that helps you. However, slotmap does not support lookups by arbitrary keys.

You can emulate this by using a HashMap<String, DefaultKey> together with a SlotMap<DefaultKey, String> though.
