Crate sled_overlay

sled-overlay is a small crate that serves as tooling to have intermediate writes to some sled database. With it, we’re able to write data into an in-memory cache, and only flush to the actual sled trees after we decide that everything in some batch was executed correctly. This gives some minimal infrastructure to be able to transparently have rollback-like functionality.

Structs

• SledDbOverlay
  An overlay on top of an entire sled::Db which can span multiple trees
