augurs - a time series toolkit for Rust

This repository contains augurs, a time series toolkit built in Rust. It aims to provide some useful primitives for working with time series, as well as the main functionality: heavily optimized models for forecasting, outlier detection, clustering, seasonality detection, changepoint detection and more. Most algorithms are based on existing R or Python implementations.

As well as the core Rust library, augurs will provide bindings to other languages such as Python and Javascript (via WASM).

Check out the demo to see what augurs can do!

[!IMPORTANT] Please note that this is not an official Grafana project, so maintenance may be a bit slower than usual. It's still early days too so expect some rough edges and changes to APIs!

Developing

This project uses just as a command runner; this will need to be installed separately. See the justfile for more information.

Some of the tasks require bacon, which will also need to be installed separately.

Releasing

Releases are made using release-plz: a PR should be automatically created for each release, and merging will perform the release and publish automatically.

Releasing the augurs Python library

The first exception to the release-plz flow is the augurs Python library, which is only released when a new tag beginning with pyaugurs is pushed. This must be done manually for now (ideally soon after the release-plz PR is merged).

E.g.:

git tag pyaugurs-v0.3.0 -m "Release pyaugurs v0.3.0"
git push --tags

Releasing the augurs npm library

The augurs npm library must also be published manually. This can be done using just publish-augurs-js; note you'll need to login with npm first.

npm login
# Log in online, etc...
just publish-augurs-js
