Rust CSV Tutorial | Read, Transform & Write CSV Files with Serde | Rust by Examples #11

Learn how to process CSV files in Rust! In this hands-on tutorial, we'll build a complete CSV data processor that reads employee data, calculates bonuses, and writes results to a new CSV file. 📚 What You'll Learn: - Using the `csv` crate for reading and writing CSV files - Serde derive macros: #[derive(Deserialize)] and #[derive(Serialize)] - Deserializing CSV rows directly into Rust structs - Filtering and transforming data with iterators - Writing structured data back to CSV format 🔧 Project: Bonus Calculator We build an employee bonus calculator that: 1. Reads employee data from employees.csv 2. Calculates bonuses (10% per year, capped at 50%) 3. Generates a formatted console report 4. Writes results to bonus_report.csv ⏱️ Timestamps: 0:00 - Introduction 0:15 - The csv Crate Explained 0:33 - Serde Derive Macros 0:51 - Create Project & Add Dependencies 1:19 - Create Sample Employee Data 2:07 - Define Employee Struct & Read CSV 3:12 - Run CSV Reader 3:36 - Add Bonus Calculation & CSV Writing 4:54 - Run Complete Demo 5:30 - Recap 5:52 - Next Lesson Preview 💻 Code Available: https://github.com/GoCelesteAI/csv_processor 🦀 Rust by Examples Series: A practical, project-based approach to learning Rust through real-world examples. #Rust #RustLang #Programming #CSV #Tutorial #Serde #DataProcessing #LearnRust
