Struct NullComplement 

pub struct NullComplement<H: HostTypes> { /* private fields */ }

Resolver-absent default Complement<H>. Implements Component<H> plus the exterior_criteria() accessor returning a reference to an embedded NullTermExpression.

Trait Implementations

impl<H: Clone + HostTypes> Clone for NullComplement<H>

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

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<H: HostTypes> Complement<H> for NullComplement<H>

type TermExpression = NullTermExpression<H>

Associated type for TermExpression.

fn exterior_criteria(&self) -> &Self::TermExpression

The formal membership criterion for this Complement: x ∈ Ext(T) iff x ∉ carrier(T). The Complement is context-dependent on the active type T (FPM_9).

impl<H: HostTypes> Component<H> for NullComplement<H>

type Datum = NullDatum<H>

Associated type for Datum.

fn member(&self) -> &[Self::Datum]

A datum value belonging to this partition component.

fn cardinality(&self) -> u64

The number of elements in this partition component. The cardinalities of the four components must sum to 2^n.

impl<H: Debug + HostTypes> Debug for NullComplement<H>

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

Formats the value using the given formatter.

impl<H: HostTypes> Default for NullComplement<H>

fn default() -> Self

Returns the “default value” for a type.

impl<H: Hash + HostTypes> Hash for NullComplement<H>

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

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl<H: PartialEq + HostTypes> PartialEq for NullComplement<H>

fn eq(&self, other: &NullComplement<H>) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl<H: Copy + HostTypes> Copy for NullComplement<H>

impl<H: Eq + HostTypes> Eq for NullComplement<H>

impl<H: HostTypes> StructuralPartialEq for NullComplement<H>
