}

A loader trait for fetching schema elements on demand.

Implementations can load from files, databases, or remote services.

Required Methods

fn load_domain(&self, name: &str) -> Result<DomainInfo>

Load a domain by name.

fn load_predicate(&self, name: &str) -> Result<PredicateInfo>

Load a predicate by name.

fn has_domain(&self, name: &str) -> bool

Check if a domain exists without loading it.

fn has_predicate(&self, name: &str) -> bool

Check if a predicate exists without loading it.

fn list_domains(&self) -> Result<Vec<String>>

List all available domain names.

fn list_predicates(&self) -> Result<Vec<String>>

List all available predicate names.

Provided Methods

fn load_domains_batch(&self, names: &[String]) -> Result<Vec<DomainInfo>>

Load a batch of domains by name.

fn load_predicates_batch(&self, names: &[String]) -> Result<Vec<PredicateInfo>>

Load a batch of predicates by name.
