# Changepoint detection models
Changepoint detection of time series.
For now it is mostly just a wrapper around the [`changepoint`] crate, with
a common `Detector` trait to allow for more implementations in future.
## Example
```rust
use augurs::changepoint::{Detector, DefaultArgpcpDetector};
let data = [0.5, 1.0, 0.4, 0.8, 1.5, 0.9, 0.6, 25.3, 20.4, 27.3, 30.0];
let changepoints = DefaultArgpcpDetector::default().detect_changepoints(&data);
// 0 is always included. 6 is the index prior to the changepoint.
assert_eq!(changepoints, vec![0, 6]);
```
## Credits
The bulk of the actual work is done by the [`changepoint`][changepoint] crate.
