PersistentMap

persistent-map provides an in-memory key-value store with async, pluggable persistence.

It combines the speed of DashMap for in-memory operations with the durability of various storage backends for persistence.

Features

• Fast in-memory access: Uses DashMap for concurrent read/write operations
• Async API: Non-blocking I/O operations for persistence
• Multiple backends: SQLite, CSV, in-memory, and extensible for more
• Type-safe: Works with any types that implement the required traits

Example

use persistent_map::{PersistentMap, Result};
use persistent_map::sqlite::SqliteBackend;
