Struct Node 

pub struct Node {
    pub id: NodeId,
    pub labels: Vec<Arc<str>>,
    pub properties: BTreeMap<PropertyKey, Value>,
}

A node in the labeled property graph.

This is the high-level representation of a node with all its data.

Fields

id: NodeId

Unique identifier.

labels: Vec<Arc<str>>

Labels attached to this node.

properties: BTreeMap<PropertyKey, Value>

Properties stored on this node.

Implementations

impl Node

pub fn new(id: NodeId) -> Self

Creates a new node with the given ID.

pub fn with_labels( id: NodeId, labels: impl IntoIterator<Item = impl Into<Arc<str>>>, ) -> Self

Creates a new node with labels.

pub fn add_label(&mut self, label: impl Into<Arc<str>>)

Adds a label to this node.

pub fn remove_label(&mut self, label: &str) -> bool

pub fn get_property(&self, key: &str) -> Option<&Value>

Gets a property from this node.

pub fn remove_property(&mut self, key: &str) -> Option<Value>

Removes a property from this node.
