Crate genetic_rs_extras 

genetic-rs-extras

This crate contains features that I thought were a bit too intrusive to include in the main genetic-rs crate, but are still useful for a lot of common projects. The current feature list is as follows:

• plotters - Adds a plot module with the struct FitnessPlotter, which implements FitnessObserver and exposes a method to plot a chart on the given plotting backend.
• indicatif - Adds a pb module, which adds both a ProgressExt trait to extend GeneticSim with a simple non-fitness-tracking progress bar, and a struct called ProgressObserver that displays the fitness values on a progress bar.

How to Use

In this guide, I’ll assume you have at least basic knowledge of the genetic-rs framework. If not, you can find the docs here. This crate mostly just plugs into the existing genetic-rs ecosystem, so it can be used the same as any other crate in the ecosystem.

For the observers (i.e. ProgressObserver and FitnessPlotter), you can add these to your FitnessEliminator:

let cool_observer = ProgressObserver::new_with_default_style(100).layer(FitnessPlotter::default());
let eliminator = FitnessEliminator::builder()
    .observer(cool_observer)
    .fitness(my_fitness_func)
    .build_or_panic();

With things like ProgressExt, you can just import them and use the method added to GeneticSim:

use genetic_rs_extras::pb::ProgressExt;

let mut sim = GeneticSim::new(...);
let pb = sim.perform_generations_pb(100, ProgressStyle::default());

Feature Requests and Contributions

Feature requests and PRs are welcome. The goal of this crate is to make using genetic-rs more convenient via features that aren’t quite suitable for the main genetic-rs repo. For super complex features, I ask that you create your own separate crate that integrates with genetic-rs, but anything that is relatively simple to implement/maintain and offers meaningful convenience/eliminates boilerplate for the genetic-rs ecosystem can be added to this crate.
