Rust Get Started

Install

Install Rust with rustup, the official installer and version manager (see rust-lang.org/tools/install), then check:

rustc --version
cargo --version

Cargo

Cargo is Rust's build tool and package manager:

cargo new hello        # creates hello/Cargo.toml and hello/src/main.rs
cd hello
cargo run              # compile and run
cargo build --release  # optimised binary in target/release/
cargo check            # type-check quickly without building
cargo fmt; cargo clippy  # format and lint

src/main.rs starts as:

fn main() {
    println!("Hello from my first Cargo project!");
}

Hello from my first Cargo project!

Dependencies ("crates") are added with cargo add serde and come from crates.io.
