Struct NullAssociativeSubalgebra 

pub struct NullAssociativeSubalgebra<H>
where
    H: HostTypes,
{ /* private fields */ }

Phase 2 (orphan-closure) — resolver-absent default impl of AssociativeSubalgebra<H>. Every accessor returns H::EMPTY_* sentinels (for scalar / host-typed returns) or a 'static-lifetime reference to a sibling Null*’s ABSENT const (for trait-typed returns). Downstream provides concrete impls; this stub closes the ontology-derived trait orphan.

Implementations

impl<H> NullAssociativeSubalgebra<H>

where H: HostTypes,

pub const ABSENT: NullAssociativeSubalgebra<H>

Absent-value sentinel. &Self::ABSENT gives every trait-typed accessor a 'static-lifetime reference target.

Trait Implementations

impl<H> AssociativeSubalgebra<H> for NullAssociativeSubalgebra<H>

where H: HostTypes,

type AssociativeSubalgebraTarget = NullAssociativeSubalgebra<H>

Associated type for AssociativeSubalgebra.

type AssociatorTriple = NullAssociatorTriple<H>

Associated type for AssociatorTriple.

fn subalgebra_ref( &self, ) -> &<NullAssociativeSubalgebra<H> as AssociativeSubalgebra<H>>::AssociativeSubalgebraTarget

The associative subalgebra selected by triple convergence.

fn associator_ref( &self, ) -> &<NullAssociativeSubalgebra<H> as AssociativeSubalgebra<H>>::AssociatorTriple

Reference to the associator triple for this convergence.

impl<H> Clone for NullAssociativeSubalgebra<H>

where H: Clone + HostTypes,

fn clone(&self) -> NullAssociativeSubalgebra<H>

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<H> Debug for NullAssociativeSubalgebra<H>

where H: Debug + HostTypes,

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl<H> Default for NullAssociativeSubalgebra<H>

where H: HostTypes,

fn default() -> NullAssociativeSubalgebra<H>

Returns the “default value” for a type.

impl<H> Hash for NullAssociativeSubalgebra<H>

where H: Hash + HostTypes,

fn hash<__H>(&self, state: &mut __H)

where __H: Hasher,

Feeds this value into the given Hasher.
