pub struct CascadeExecutor<'a> { /* private fields */ }

Executes cascade operations for delete.

Implementations

impl<'a> CascadeExecutor<'a>

pub fn new(catalog: &'a Catalog, engine: &'a StorageEngine) -> Self

Create a new cascade executor.

pub fn process_delete( &self, entity: &str, entity_id: [u8; 16], tx: &mut Transaction<'_>, ) -> Result<CascadeResult, Error>

Process cascades for a delete operation.

This method checks all relations that reference the entity being deleted and applies the appropriate cascade behavior.

pub fn can_delete(&self, entity: &str, entity_id: [u8; 16]) -> Result<(), Error>

Check if deleting an entity is allowed (without actually performing cascades).

This is useful for validation before committing.
