Struct PluginRegistry 

pub struct PluginRegistry { /* private fields */ }

A complete generation. All maps are built before this value is returned; consumers receive it through Arc and cannot mutate its contents.

Implementations

impl PluginRegistry

pub fn invoke_planner_support( &self, support_id: [u8; 16], arguments: &[NormalizedPredicateArgument<'_>], limits: InvocationLimits, ) -> Result<PlannerSupportOutcome, PluginInvocationError>

Invoke a database-bound planner support callback with a closed, versioned predicate frame. The plugin can only return declarative key spans; every span is decoded and canonicalized by the host.

pub fn encode_operator_class_key( &self, object_id: [u8; 16], value: &Value, limits: InvocationLimits, ) -> Result<Value, PluginInvocationError>

Produce one core-owned physical key for an admitted operator class.

B-tree/bitmap classes use their bounded encoder callback. Hash classes only emit semantic components into the host sink; the core HashIndex remains the sole owner of hashing algorithm and seed.

pub fn invoke_scalar_function( &self, object_id: [u8; 16], arguments: &[Value], limits: InvocationLimits, ) -> Result<Value, PluginInvocationError>

pub fn invoke_function_batch( &self, object_id: [u8; 16], rows: &[Vec<Value>], limits: InvocationLimits, ) -> Result<Vec<Value>, PluginInvocationError>

pub fn validate_external_value( &self, value: &Value, ) -> Result<(), PluginInvocationError>

pub fn parse_external_text( &self, type_ref: ExternalTypeRef, text: &str, ) -> Result<Value, PluginInvocationError>

pub fn format_external_text( &self, value: &Value, ) -> Result<String, PluginInvocationError>

pub fn parse_external_binary( &self, type_ref: ExternalTypeRef, bytes: &[u8], ) -> Result<Value, PluginInvocationError>

pub fn format_external_binary( &self, value: &Value, ) -> Result<Vec<u8>, PluginInvocationError>

pub fn external_equal( &self, left: &Value, right: &Value, ) -> Result<bool, PluginInvocationError>

pub fn external_compare( &self, left: &Value, right: &Value, ) -> Result<Ordering, PluginInvocationError>

pub fn external_hash_components( &self, value: &Value, ) -> Result<Vec<HashComponent>, PluginInvocationError>

pub fn operator_by_package_and_local_id( &self, package_id: &[u8; 16], local_id: &str, ) -> Option<&Arc<RegisteredOperator>>

pub fn operator_class_by_package_and_local_id( &self, package_id: &[u8; 16], local_id: &str, ) -> Option<&Arc<RegisteredOperatorClass>>

pub fn planner_support( &self, id: &[u8; 16], ) -> Option<&Arc<RegisteredPlannerSupport>>

pub fn planner_support_by_package_and_local_id( &self, package_id: &[u8; 16], local_id: &str, ) -> Option<&Arc<RegisteredPlannerSupport>>
