Implementations

impl StoredConstraintKind

pub fn type_tag(&self, entity: StoredIndexEntity) -> &'static str

pub fn requires_backing_index(&self) -> bool

True for constraints that need a backing range index. Used by the store layer to decide whether to register/drop one alongside the catalog entry.

pub fn requires_existence(&self) -> bool

True for constraints that require every covered property to be present (existence semantics). Property uniqueness alone does NOT require all properties to exist.

pub fn requires_uniqueness(&self) -> bool

True for constraints that enforce uniqueness across the full property tuple.

Trait Implementations

impl Clone for StoredConstraintKind

fn clone(&self) -> StoredConstraintKind

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for StoredConstraintKind

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for StoredConstraintKind

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for StoredConstraintKind

fn eq(&self, other: &StoredConstraintKind) -> 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 Serialize for StoredConstraintKind

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
