Project mention: I built a Rust replacement for ccusage — 1,742x faster, near-zero overhead | dev.to | 2026-05-08
Toki is a direct, drop-in replacement for ccusage. It's a Rust daemon that indexes your sessions incrementally and serves reports from an embedded LSM store (fjall, used as a TSDB). Docker-style architecture: one daemon ingests, multiple clients read.

Project mention: Lightning Memory-Mapped Database Manager (LMDB) 1.0 | news.ycombinator.com | 2026-07-02
Yup! Same, I'm the maintainer of the main LMDB Rust wrapper [1] and I was maintaining heed and heed3 (because 1.0 was available from the mdb.master3 branch).
But now that it's LMDB 1.0, I need to find a better way to make it be the official one but I can't really rename heed3 into heed and heed into heed-0.9...

nkv
Share your state between services using persisted key value storage with notification option (by nkval)

Project mention: Ferrokey – embedded B-tree KV store in Rust, WAL crash recovery, zero deps | news.ycombinator.com | 2026-05-06
The crash recovery test was the most interesting to write — it simulates a crash by appending WAL records without writing to the db file, then reopening.
