Crate signature_rs 

signature-rs

A Rust library for computing log signatures from path data.

Quick Start

use signature_rs::prelude::*;
use ndarray::array;
use ordered_float::NotNan;

let path = array![[0.0, 0.0], [1.0, 0.5], [2.0, 1.0]];
let path = path.mapv(|v| NotNan::new(v).expect("value to be a number"));
let builder = LogSignatureBuilder::<ENotation>::new()
    .with_num_dimensions(2)
    .with_max_degree(3);
let log_sig = builder.build_from_path(&path.view());

Re-exports

pub use log_sig::LogSignature;

pub use log_sig::LogSignatureBuilder;
