// Rust guideline compliant 2026-02-28

//! `wasm-dbms-memory` provides runtime-agnostic memory abstraction and
//! page management for the wasm-dbms framework.
//!
//! This crate contains:
//! - [`MemoryProvider`] trait for abstracting memory backends
//! - [`HeapMemoryProvider`] for testing
//! - [`MemoryManager`] for page-level memory operations
//! - [`SchemaRegistry`] for table schema persistence
//! - [`AccessControl`] trait for pluggable access control
//! - [`AccessControlList`] for identity-based access control
//! - [`NoAccessControl`] for runtimes without access control
//! - [`TableRegistry`] for record-level storage and retrieval
//! - [`AutoincrementLedger`] for autoincrement column value tracking
