Struct Node 

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

A node with its labels and properties fully loaded.

This is what you get back from LpgStore::get_node(). For bulk operations, the store works with NodeRecord internally.

Example

use grafeo_core::graph::lpg::Node;
use grafeo_common::types::NodeId;

let mut person = Node::new(NodeId::new(1));
person.add_label("Person");
person.set_property("name", "Alice");
person.set_property("age", 30i64);

assert!(person.has_label("Person"));

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

Removes a label from this node.

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

Checks if this node has the given label.

pub fn set_property( &mut self, key: impl Into<PropertyKey>, value: impl Into<Value>, )

Sets a property on this node.

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.
