assist-sys

This is a Rust crate which provides bindings for ASSIST.

The generated bindings are currently only for a statically linked version of assist. This isn't for a deep reason; it's just that I expect that dynamically linking to assist is pretty unusual, and it's easier to provide a statically linked sys crate.

Running tests

Tests require ephemeris data. Get them by running 'make' in the testdata directory. This will use cURL to download ephemerides files. They're large - 600MB - but necessary.

Then, 'cargo test' runs tests.
