From Jerome's Readme:
An implementation of the largest triangle three buckets (lttb) algorithm for time series downsampling as described in Downsampling Time Series for Visual Representation. This is a Rust port of the original Javascript implementation.
This implementation is heavily based and inspired from his original. Some QOL updates and datatype differences, such as using rust_decimal and offering output types to work generically or with chrono or time (both behind features).
``` rust use downsample_oxide::*;
fn main() { let dps = Vec::from([ DataPoint::new(firstdayofmonth(1), Decimal::from(10)), DataPoint::new(firstdayofmonth(2), Decimal::from(12)), DataPoint::new(firstdayofmonth(3), Decimal::from(8)), DataPoint::new(firstdayofmonth(4), Decimal::from(10)), DataPoint::new(firstdayof_month(5), Decimal::from(12)), ]);
let output = dps.downsample(3)
} ```
