Struct SimpleNode 

pub struct SimpleNode { /* private fields */ }

A graph node (Java SimpleNode): unique alias, one or more types, and a property bag. Shared by Arc; equality is by node id.

Implementations

impl SimpleNode

pub fn get_id(&self) -> &str

pub fn get_alias(&self) -> &str

pub fn get_types(&self) -> HashSet<String>

pub fn add_type(&self, node_type: &str) -> Result<(), AppError>

pub fn reset_types(&self, initial: &str) -> Result<(), AppError>

Replace all types with one initial type (the Java Playground’s update node mutates the live type set; this is the explicit analog).

pub fn clear_properties(&self)

Remove all properties (the Java Playground’s update node analog).

pub fn remove_type(&self, node_type: &str) -> Result<(), AppError>

A node keeps at least one type (Java parity).

pub fn get_properties(&self) -> HashMap<String, Value>

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

pub fn add_property(&self, key: &str, value: Value) -> Result<(), AppError>

pub fn remove_property(&self, key: &str) -> Result<(), AppError>
