Trait ItemKey 

pub trait ItemKey:
    Clone
    + Eq
    + Hash
    + Debug
    + 'static { }

A stable, hashable identity for a row/node. Blanket-implemented for every Clone + Eq + Hash + Debug + 'static type, so usize, NodeId, i64, String, Uuid, … all qualify with no extra work.

In-memory models use positional keys (usize for ListModel, NodeId for TreeModel); external sources use their own domain key (an entity id), which is exactly what removes the need to mirror them into a built-in model.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
