Trait CanonicalIncidenceIdentity 

pub trait CanonicalIncidenceIdentity: IncidenceBase {
    type CanonicalIncidenceId: TopologyId;

    // Required method
    fn canonical_incidence_id(
        &self,
        incidence: Self::IncidenceId,
    ) -> Self::CanonicalIncidenceId;
}

Optional local-to-canonical incidence identity capability.

Views implement this trait only when they guarantee a stable canonical ID for every visible incidence in the view’s documented identity scope.

Performance

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

Required Associated Types

type CanonicalIncidenceId: TopologyId

Canonical incidence ID guaranteed by this view.

Performance

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

Required Methods

fn canonical_incidence_id( &self, incidence: Self::IncidenceId, ) -> Self::CanonicalIncidenceId

Returns the canonical ID for a visible local incidence.

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".
