Trait CanonicalElementIdentity 

Source 
pub trait CanonicalElementIdentity: TopologyBase {
    type CanonicalElementId: TopologyId;

    // Required method
    fn canonical_element_id(
        &self,
        element: Self::ElementId,
    ) -> Self::CanonicalElementId;
}
Expand description

Optional local-to-canonical element identity capability.

Views implement this trait only when they guarantee a stable canonical ID for every visible element in the view’s documented identity scope. The canonical ID is a substrate identity, not a Python label or domain identifier.

§Performance

Lookup should be O(1) unless an implementation documents a weaker contract.

Required Associated Types§

Source

type CanonicalElementId: TopologyId

Canonical element ID guaranteed by this view.

§Performance

Values should be O(1) to copy, compare, order, hash, and debug-format.

Required Methods§

Source

fn canonical_element_id( &self, element: Self::ElementId, ) -> Self::CanonicalElementId

Returns the canonical ID for a visible local element.

§Performance

Expected O(1) unless the implementation documents otherwise.

Dyn Compatibility§

This trait is dyn compatible.

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