Trait Identified 

pub trait Identified {
    // Required method
    fn key(&self) -> Key;

    // Provided methods
    fn handle(&self) -> u64 { ... }
    fn model_id(&self) -> ModelId<Self>
       where Self: Sized { ... }
}

Gives an element the stable key its paths are addressed by. Implemented by #[derive(Observable)] from the #[obs(key)] field.

Required Methods

fn key(&self) -> Key

The element’s key, read from the #[obs(key)] field.

Provided Methods

fn handle(&self) -> u64

The key as its path handle: identity for u64 keys, interned otherwise.

fn model_id(&self) -> ModelId<Self>

where Self: Sized,

The typed id over the same handle. (Named to stay clear of the generated accessor for an id field, which nearly every model has.)

Dyn Compatibility

This trait is dyn compatible.

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