Struct Id

pub struct Id<E>where
    E: Entity,
{ /* private fields */ }

Description

Strongly typed identifier for an entity in the Graph Federation.

The phantom parameter carries both the entity kind and (through Entity::Graph) the graph it belongs to. fn() -> E keeps the type covariant and Send + Sync regardless of E.
