Crate delfi 

Delfi is a crate which seeks to minimize the code needed to save your data to a csv-file. No matter which form your data takes it should be easy to save it to csv! The crate is centralized around two core concept:

• The Datapoint: A set of data elements which can be recorded to csv-format
• The Dataset: A collection of datapoints, optionally with labels

A quick example using std-arrays:

use delfi::Dataset;

let t = [0.0, 0.5, 1.0];
let x = [1.0, 2.0, 4.0];

let ds = Dataset::from_columns([t, x]).with_labels(["time", "length"]);
ds.save("./resources/data/examples/basic.csv").unwrap();

Here is a slighlty more complex example using ndarrays:

use delfi::dataset;
use ndarray::Array;

const N: usize = 1000;
let x = Array::linspace(0., 10., N+1);
let y = Array::logspace(10., 0., 2., N+1);

let dataset = dataset!{
    "x" => x,
    "y" => y,
};

let directory = std::fs::canonicalize("./resources/data/examples/").unwrap();
let filepath = directory.join("ndarray.csv");
dataset.save(&filepath).unwrap();
