kvdb-overlay

kvdb-overlay

This Rust library serves as a minimal overlay mechanism for various key-value embedded databases.

This mechanism enables us to simulate changes in a database/tree so that keys and values can be dynamically mutated, while avoiding having to change the underlying database. With this, we can perform changes to the trees and access the latest changes in-memory, and then only when we're satisfied with the results, we can actually atomically write it into the actual database.

This functionality can also serve as a rollback-like mechanism for the database.

Currently supported databases:

• sled
• fjall

Usage examples are offered in the repository as test units, and docs can be found on docs.rs/kvdb-overlay.
