Expand description

Runtime value in query execution. Extends PropertyValue with graph entity references.

Variants§

Null

Null value.

Bool(bool)

Boolean value.

Int64(i64)

64-bit integer value.

Float64(f64)

64-bit floating-point value.

String(String)

UTF-8 string value.

Bytes(Vec<u8>)

Raw byte array value.

List(Vec<Value>)

Ordered list of values.

Node(NodeId)

A node entity reference.

Edge(EdgeId)

An edge entity reference.

DateTime(i64)

DateTime as milliseconds since Unix epoch.

Subgraph(SubgraphId)

A subgraph entity reference.

Hyperedge(HyperEdgeId)

A hyperedge entity reference.

TemporalNode(NodeId, i64)

A node reference at a specific point in time (lazy VersionStore resolution). NN-001: TemporalRef resolves to the versioned node state when properties are accessed.

Trait Implementations§

impl Clone for Value

fn clone(&self) -> Value

Returns a duplicate of the value. Read more

1.0.0 · Source§

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

Performs copy-assignment from source. Read more

impl Debug for Value

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

Formats the value using the given formatter. Read more

impl From<PropertyValue> for Value

Convert from storage PropertyValue to executor Value.

fn from(pv: PropertyValue) -> Self

Converts to this type from the input type.

impl PartialEq for Value

fn eq(&self, other: &Value) -> bool

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

1.0.0 · Source§

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 TryFrom<Value> for PropertyValue

Convert from executor Value to storage PropertyValue (for SET operations).

type Error = String

The type returned in the event of a conversion error.

fn try_from(v: Value) -> Result<Self, Self::Error>

Performs the conversion.
