Struct NodeTypeDef 

pub struct NodeTypeDef {
    pub description: Option<String>,
    pub properties: BTreeMap<String, PropertyDef>,
    pub subtypes: Option<BTreeMap<String, SubtypeDef>>,
    pub parent_type: Option<String>,
}

Definition of a node type in the ontology.

If subtypes is Some, then add_node requires a subtype parameter and properties are validated against the subtype’s definition. If subtypes is None, the type works as before (D-024 backward compat).

Fields

description: Option<String>

properties: BTreeMap<String, PropertyDef>

subtypes: Option<BTreeMap<String, SubtypeDef>>

Optional subtype definitions. When present, add_node must specify a subtype and properties are validated per-subtype (D-024).

parent_type: Option<String>

RDFS-level class hierarchy (Step 2). If set, this type is a subclass of parent_type. Queries for the parent type include this type. Edge constraints accepting the parent type also accept this type. Properties are inherited from the parent (child overrides on conflict).

Trait Implementations

impl Clone for NodeTypeDef

fn clone(&self) -> NodeTypeDef

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for NodeTypeDef

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for NodeTypeDef

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for NodeTypeDef

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
