Modules

integration

Cache management and integration utilities

parameterized

Parameterized plan support for literal extraction and binding

prepared_statement

Prepared statement caching for optimized query execution

table_extractor

Extract table names from AST for cache invalidation

Structs

CacheStats

Statistics about cache performance

QueryPlanCache

Generic type-erased cache for storing parsed AST and plans This intentionally avoids caching results - plans are still executed
