# xs

This is a command-line tool (`xs`) and a Rust library (`xs_lib`) for recording
and retrieving sequential streams of payloads. It uses [Lightning Memory-Mapped
Database](http://www.lmdb.tech/doc/)
([LMDB](https://docs.rs/lmdb-rkv/0.14.0/lmdb/)) for efficient and reliable
local embedded storage.

```

IDs are [SCRU128](https://github.com/scru128/rust)s.
