This Rust library serves as a minimal overlay mechanism for thesled embedded database.

This mechanism enables us to simulate changes in a sled database/treeso that keys and values can be dynamically mutated, while avoidinghaving to change the underlying database. With this, we can performchanges to the sled trees and access the latest changes in-memory,and then only when we're satisfied with the results, we can actuallyatomically write it into the actual database.

This functionality can also serve as a rollback-like mechanismfor sled.

Usage examples are offered in the repository as test units, and docscan be found ondocs.rs/sled-overlay.
