Rust makes concurrency safe and predictable. You can create threads using std::thread, and communicate between them using channels from std::sync::mpsc. This lets you write multi-threaded programs without fear of data races or unsafe behavior. The first time I used threads…
In this project, you will build a basic command-line to-do list app in Rust. It stores tasks in a SQLite database using rusqlite, and accepts commands from the user via clap. This teaches you real-world CRUD operations: create, read, update,…
The rusqlite crate is the easiest way to interact with SQLite databases in Rust. It allows you to create tables, insert rows, query data, and handle results using type-safe Rust code. When I needed to save user data in a…
Borrow checker errors in Rust usually mean your code is accessing memory in an unsafe or conflicting way. These errors often look cryptic at first, but they are actually protecting you from common bugs like use-after-free, data races, and memory…
Rust gives you full control over memory without needing a garbage collector. It uses the stack for fixed-size, known-at-compile-time values, and the heap for dynamically sized data. Understanding how Rust chooses where to store data helps you write faster and…
The regex crate gives Rust full support for regular expressions. It lets you search, validate, extract, and replace text using familiar patterns just like in JavaScript, Python, or other languages. I found myself reaching for regex when parsing logs in…
The chrono crate is the standard way to work with dates and times in Rust. It helps you parse, format, and perform arithmetic on dates and times, whether you are building logs, schedulers, or working with timestamps from APIs. I…
In this mini-project, you will build a simple command-line application that fetches real-time weather data from a public API. You will use reqwest to make HTTP requests, serde to parse the JSON response, and clap to accept city names from…
The serde crate is the standard for serializing and deserializing data in Rust. It allows you to convert Rust structs to JSON and back using powerful macros. Combined with serde_json, it gives you type-safe and flexible control over reading and…
