RFC: redb (embedded key-value store) nearing version 1.0

redb is an embedded key-value store, similar to lmdb and rocksdb. It differs in that it's written in pure Rust, provides a typed API, is entirely memory safe, and is much simpler than rocksdb.

It's designed from the ground up to be simple, safe, and high performance.

I'm planning to release version 1.0 soon, and am looking for feedback on the file format, API, and bug reports. If you have general comments please leave them in this issue, otherwise feel free to open a new one!
