Struct CatalogConstraintValidator 

pub struct CatalogConstraintValidator { /* private fields */ }

Validates schema constraints during mutation operations using the Catalog.

Checks type definitions, NOT NULL constraints, and UNIQUE constraints against registered node/edge type definitions.

Implementations

impl CatalogConstraintValidator

pub fn new(catalog: Arc<Catalog>) -> Self

Creates a new validator wrapping the given catalog.

pub fn with_graph_name(self, name: String) -> Self

Sets the graph name for graph-type-bound validation.

pub fn with_store(self, store: Arc<dyn GraphStoreMut>) -> Self

Attaches a graph store for UNIQUE constraint enforcement.

Trait Implementations

impl ConstraintValidator for CatalogConstraintValidator

fn validate_node_property( &self, labels: &[String], key: &str, value: &Value, ) -> Result<(), OperatorError>

Validates a single property value for a node with the given labels.

fn validate_node_complete( &self, labels: &[String], properties: &[(String, Value)], ) -> Result<(), OperatorError>

Validates that all required properties are present after creating a node.

fn check_unique_node_property( &self, labels: &[String], key: &str, value: &Value, ) -> Result<(), OperatorError>

Checks UNIQUE constraint for a node property value.

fn validate_edge_property( &self, edge_type: &str, key: &str, value: &Value, ) -> Result<(), OperatorError>

Validates a single property value for an edge of the given type.

fn validate_edge_complete( &self, edge_type: &str, properties: &[(String, Value)], ) -> Result<(), OperatorError>

Validates that all required properties are present after creating an edge.

fn validate_node_labels_allowed( &self, labels: &[String], ) -> Result<(), OperatorError>

fn validate_edge_endpoints( &self, edge_type: &str, source_labels: &[String], target_labels: &[String], ) -> Result<(), OperatorError>

Validates that edge endpoints have the correct node type labels.

fn inject_defaults( &self, labels: &[String], properties: &mut Vec<(String, Value)>, )

Injects default values for properties that are defined in a type but not explicitly provided.
