Struct LazySymbolTable 

pub struct LazySymbolTable { /* private fields */ }

A symbol table with lazy loading support.

Elements are loaded on-demand from a SchemaLoader, reducing memory usage for large schemas.

Implementations

impl LazySymbolTable

pub fn new(loader: Arc<dyn SchemaLoader>) -> Self

Create a new lazy symbol table.

Examples

use tensorlogic_adapters::{LazySymbolTable, FileSchemaLoader};
use std::sync::Arc;

let loader = Arc::new(FileSchemaLoader::new("/tmp/schema"));
let lazy_table = LazySymbolTable::new(loader);

pub fn with_strategy( loader: Arc<dyn SchemaLoader>, strategy: LoadStrategy, ) -> Self

Create a lazy table with a specific loading strategy.

pub fn get_domain(&self, name: &str) -> Result<Option<DomainInfo>>

Get a domain, loading it if necessary.

pub fn get_predicate(&self, name: &str) -> Result<Option<PredicateInfo>>

Get a predicate, loading it if necessary.

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

List all available domains (without loading them).

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

List all available predicates (without loading them).

pub fn preload_domains(&self, names: &[String]) -> Result<()>

Preload a batch of domains.

pub fn preload_predicates(&self, names: &[String]) -> Result<()>

Preload a batch of predicates.

pub fn stats(&self) -> LazyLoadStats

Get loading statistics.

pub fn clear_cache(&self)

Clear the cache and force reload.

pub fn loaded_domain_count(&self) -> usize

Get the number of loaded domains.

pub fn loaded_predicate_count(&self) -> usize

Get the number of loaded predicates.

pub fn as_symbol_table(&self) -> Arc<RwLock<SymbolTable>>

Get a read-only reference to the loaded symbol table.

Note: This only includes loaded elements.
