Enum PropertyType 

pub enum PropertyType {
    String,
    Int,
    Float,
    Bool,
    Date,
    Datetime,
    List(Box<PropertyType>),
    Enum(SmolStr, Vec<SmolStr>),
    Opaque(SmolStr),
    Any,
}

The propertable-value type language. Intentionally simpler than the full Cypher value type — schemas describe what values are stored.

Variants map 1:1 to spec §8.2’s type lattice; the variant names are self-documenting. #[allow(missing_docs)] applies to the primitive variants; variants with nontrivial invariants (Enum, Opaque) keep their own docstrings.

Variants

String

Int

Float

Bool

Date

Datetime

List(Box<PropertyType>)

Enum(SmolStr, Vec<SmolStr>)

A closed enum carrying its name and variant names.

Spec §8.2 shape: Enum(SmolStr, Vec<SmolStr>) — tuple variant.

Opaque(SmolStr)

An opaque typed value the consumer chooses not to model structurally.

Unification invariant (spec §8.2): Opaque(n) unifies with Opaque(n) (same symbolic name) and with PropertyType::Any; every other pairing is a type error. This rule lives in the unification layer (cyrs-sema); the shape here only carries the symbolic name. Two opaque types with different names never unify.

Any

Fallback: any property value. Equivalent to “type unknown”.

Not in spec §8.2’s normative 9-variant set; retained as an internal fallback for ReturnTy::Dynamic cloning. Consumers should prefer the typed variants.

Trait Implementations

impl Clone for PropertyType

fn clone(&self) -> PropertyType

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PropertyType

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for PropertyType

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for PropertyType

fn eq(&self, other: &PropertyType) -> 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 PropertyType

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Eq for PropertyType
