Struct AstSubject 

pub struct AstSubject {
    pub identity: String,
    pub labels: Vec<String>,
    pub properties: HashMap<String, Value>,
}

Subject data - identity, labels, and properties

The subject provides “information about the elements” in a pattern.

Examples

Node with identity and label:

{
  "identity": "alice",
  "labels": ["Person"],
  "properties": {}
}

Anonymous node with properties:

{
  "identity": "",
  "labels": [],
  "properties": {"name": "Alice", "age": 30}
}

Fields

identity: String

Identity (empty string if not specified)

labels: Vec<String>

Labels (type tags)

properties: HashMap<String, Value>

Properties (arbitrary JSON values)

Values use mixed serialization:

• Simple types: native JSON (string, number, boolean, array, object)
• Complex types: tagged objects (Symbol, Integer, Decimal, Range, etc.)

Trait Implementations

impl Clone for AstSubject

fn clone(&self) -> AstSubject

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for AstSubject

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for AstSubject

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for AstSubject

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
