Introduction to Rust and Cargo

What is Rust and why should I learn it?

Rust is a systems programming language designed for performance, safety, and concurrency.

It was created from the ground up with a focus on preventing common errors errors like null pointer dereferencing, data races, and buffer overflows to happen.

What are the use-cases for Rust?

  • Operating Systems
  • Device Drivers
  • Web Servers
  • Scientific Computing
  • Gaming

What are the highlights of Rust?

  • Safe memory management without garbage collection

  • Strong support for concurrency and parallelism

  • High performance

  • Expressiveness and powerful abstractions

  • Built-in cross platform support

  • Growing community and ecosystem

What is Cargo and how to use it?

Cargo is the package manager and build system for Rust. It is an integral part of the Rust programming language ecosystem.

Create a Project

cargo new --bin <project name> # Create a new binary project.
cargo new --lib <project name> # Create a new library project.

Manage it with git!

Building

cargo build            # Build in debug mode.
cargo build --release  # Build in release mode.

Running

cargo run            # Build and run in debug mode.
cargo run --release  # Build and run in release mode.

Testing

cargo test            # Run tests in debug mode.
cargo test --release  # Run tests in release mode.

Formatting and Linting

cargo fmt     # Format the code.
cargo clippy  # Lint the code.
