Rust

Basic

These concepts cover the fundamental features and syntax of Rust. They are necessary for writing simple programs and laying a solid foundation in Rust development.

  1. Introduction to Rust

    • Learn about Rust's role in systems programming and understand the toolchain, including rustc, Cargo, and the Rust ecosystem.

    • Explore Rust's key concepts, like ownership and borrowing, and understand the significance of these concepts.

    • Reason: Understanding Rust's unique ownership model is crucial for writing efficient and safe code.

    • Example Task: Set up a new Rust project using Cargo and create a basic "Hello, World!" application.

  2. Working with Variables, Data Types, and Functions

    • Learn to declare and use variables, data types, and functions in Rust, including immutability and shadowing.

    • Explore basic data types like integers, floating points, and booleans, and understand the use of tuples and arrays.

    • Reason: Mastery of variables and data types is essential for managing data and logic in Rust programs.

    • Example Task: Create a function that takes two integers, adds them, and returns the result.

  3. Control Flow in Rust

    • Understand Rust's control flow structures, including if, else, match, and loops (for, while).

    • Learn to implement basic control flow logic in Rust to make decisions and repeat operations.

    • Reason: Control flow structures are fundamental for directing the execution of code based on conditions.

    • Example Task: Write a function that uses a match statement to categorize numbers as positive, negative, or zero.

  4. Ownership and Borrowing Basics

    • Explore the concepts of ownership, borrowing, and references and how they enforce memory safety in Rust.

    • Learn to handle different types of borrowing (& and &mut) and understand the rules of ownership transfer.

    • Reason: Ownership and borrowing are core concepts in Rust that prevent memory errors and data races.

    • Example Task: Implement a function that borrows a string slice and prints its contents without taking ownership.

  5. Working with Structs and Enums

    • Learn how to define and use structs to create custom data types and enums to represent different variants of a value.

    • Understand how to implement methods on structs and enums for encapsulating behaviour.

    • Reason: Structs and enums are powerful tools for modelling data and behaviour in Rust applications.

    • Example Task: Create a struct to represent a rectangle and implement a method to calculate its area.

  6. Basic Error Handling

    • Learn about Rust’s error-handling mechanisms, including Result and Option types.

    • Explore how to propagate errors using the ? Operator and handle them with match or unwrap.

    • Reason: Proper error handling is essential for building robust and reliable applications in Rust.

    • Example Task: Write a function that reads a file and returns its content or an error if the file doesn’t exist.

  7. Working with Collections

    • Explore Rust’s standard collections, such as Vec, HashMap, and HashSet, and understand their use cases.

    • Learn to add, remove, and iterate over elements in these collections efficiently.

    • Reason: Collections are fundamental for managing groups of data and performing operations on them.

    • Example Task: Implement a function that takes a list of integers and returns the sum of all elements using a Vec.
