RustMeUp: Exploring Rust for Data Science

Intro to Rust

Rust is a modern systems programming language that is designed to be safe, concurrent, and efficient. It's open-source, general-purpose, and has gained popularity due to its performance and memory safety, especially when compared to languages like C++.

For new users wondering, "Why should I use Rust?", consider Rust's primary benefit - its ability to handle low-level tasks such as memory management and concurrency efficiently. Rust’s memory safety guarantees, enforced at compile time, deliver a high level of performance and prevent many types of common errors in other languages. This makes Rust ideal for systems programming, game development, and other performance-critical applications.

But, is Rust beneficial for the data science community? The short answer is yes. Rust's speed and safety characteristics make it a worthy language to consider for data science tasks.

Data Science with Rust

1. What does Rust offer for data science?

Rust may not be the first language that comes to mind when thinking about data science due to the dominance of languages like Python and R in the field. However, Rust's increasing popularity and unique features position it as a strong contestant in the data science world.

Firstly, Rust's speed gives it a distinct advantage. Data science often requires dealing with large datasets, and Rust's efficiency can make data processing much faster compared to languages like Python.

Secondly, Rust's memory safety means less time spent debugging errors. Dealing with nasty memory bugs can be a bane of programming in many languages, but Rust's compile-time checks help to eliminate this kind of problem.

Thirdly, Rust might be safer for big data applications. Since Rust guarantees memory safety without a garbage collector, it simplifies concurrent programming by eliminating common bugs that can lead to data races.

Lastly, with the rust-ml initiative, there are increasing efforts made to create a high-quality, high-performance, and easy to use machine learning library.

2. How do I start with Rust for data science?

Starting with Rust for data science is as simple as installing the Rust programming language, picking up the basics of the Rust syntax, and familiarizing yourself with the available libraries for data science.

The standard way to install Rust is from the official download page. Once you've installed Rust, you can start off by learning the basics of Rust - the syntax, data types, control statements, loops, etc. A basic understanding of programming concepts would suffice to pick up Rust.

One fantastic resource to learn Rust is the book "The Rust Programming Language" by Steve Klabnik and Carol Nichols, also known as the 'Rust Book'. The book provides a comprehensive introduction to the language, it's perfectly suitable for beginners and also dives into some advanced topics.

As for libraries, for numerical computing you have ‘ndarray’ similar to NumPy in Python, 'statrs' for statistics, and 'rustlearn' and 'leaf' for machine learning.

3. What are some data science libraries in Rust?

Rust's ecosystem offers several libraries for data science, though it has some way to go to match Python’s rich ecosystem. Here are some popular libraries:

  • ndarray: A library for multi-dimensional, array-based data. It provides methods for advanced computations and is comparable to NumPy in Python.
  • rustlearn: It offers algorithms for linear models, decision trees, and clustering, among others. It's Rust’s answer to Python's Scikit-learn.
  • statrs: A statistical computation library that provides a host of statistical distributions, and statistical and mathematical functions.
  • leaf: Leaf is a Machine Intelligence Framework for hackers to build classical, deep learning, and reinforcement learning.
  • plotlib: Plotlib lets you draw in Rust. It's a plotting library that can create scatter plots, histograms, and line plots.
  • Polars: Polars is a blazingly fast DataFrame library implemented in Rust and accessible from Python, based on Apache Arrow.

4. What are the limitations of using Rust for data science?

While Rust has substantial potential for use in data science, there exist limitations, some of which might make data scientists have second thoughts about switching to Rust:

  • Limited Ecosystem: Unlike Python, which has a rich array of mature data science libraries, Rust’s ecosystem is smaller and less mature, though swiftly growing.
  • Learning Curve: While Rust's safety and control features contribute to its appeal, they also add complexity which translates to a steeper learning curve compared to languages like Python.
  • Less Community and Resources: The community of Rust data scientists is significantly smaller than for some other languages. Therefore, resources, tutorials, and solutions to common problems can be harder to find.


While the current state of Rust for data science is promising, it may not be ready for everyone to make an immediate switch, particularly for those used to the conveniences of more established languages. However, for those who value speed, memory safety, and concurrent processing, Rust could be a powerful tool in their data science toolkit.

For anyone willing to climb the learning curve, Rust can offer an efficient, robust, and enjoyable data science programming experience. It is a language with clear potential - not just for systems programming, but for data science as well. The world of Rust and data science is waiting to be explored further!
