The Data analysis in Rust book is a "learn by example" guide to data analysis in Rust. It assumes minimal knowledge of data analysis and minimal familiarity with Rust and its tooling.
The first section explores concepts related to data analysis in Rust, the crates (libraries) used in the book and how to collect the data necessary for the examples.
The second section explains how to read and write various types of data (e.g. .csv and .parquet), including larger-than-memory data. This section also focuses on the various locations that data can be read from and written to, including local data, cloud-based data and databases.
The third section demonstrates how to transform data by adding and removing columns, filtering rows, pivoting the data and joining various data together.
The fourth section shows how do summary statistics, such as counts, totals, means and percentiles, with and without survey weights. It also gives some examples of hypothesis testing.
The fifth and last section has examples of publication avenues, such as exporting summary statistics to excel, plotting results and writing markdown reports.
This repository works both as the repository for this mdBook and a runnable copy of all the examples in the book. All examples in the book can be found in the examples folder. You can get access to all the examples by running git clone "https://github.com/EricFecteau/rust-data-analysis.git" and then running cargo run -r --example name_of_example.
While this book uses larger-than-memory data (at least larger than 16 GB of RAM), at no point does the example bring all the data into memory at the same time. The memory spikes at a maximum of around 5 GB or so on some processes. Therefore, these examples can be run on pretty much any modern computer.
