rusqlite-pool

A minimal connection pool for rusqlite, suitable for async and multi-threaded usage.

Provides connection pools and handles for sync and async usages:

• ConnectionPool: A fixed-capacity, thread-safe queue of rusqlite::Connections available for usage.
• ConnectionHandle: A temporary handle to a connection.
• AsyncConnectionPool: A thin wrapper around ConnectionPool that uses Semaphores for orderly async access to database connections.
• AsyncConnectionHandle: A thin wrapper around ConnectionHandle that manages the associated SemaphorePermit.

The async counterparts are behind feature tokio.
