Trait for validating schema constraints during mutation operations.

Implementors check type definitions, NOT NULL, and UNIQUE constraints before data is written to the store.

Required Methods

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.

Checks type compatibility and NOT NULL constraints.

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

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

Checks NOT NULL constraints for properties that were not explicitly set.

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

Checks UNIQUE constraint for a node property value.

Returns an error if a node with the same label already has this 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.

Provided Methods

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

Validates that the node labels are allowed by the bound graph type.

fn validate_edge_type_allowed( &self, edge_type: &str, ) -> Result<(), OperatorError>

Validates that the edge type is allowed by the bound graph type.

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.
