Setup

To start to use rust on UNIX-like system it's enough to run:

$ curl https://sh.rustup.rs -sSf | sh

rustup will install the latest stable version. Then to add cargo to your system PATH, include the following line to your rc file:

export PATH="$HOME/.cargo/bin:$PATH"

Usage

Firstly check if rust and cargo are properly set:

$ rustc -V; cargo -V

If all is good the output will show the version of both binaries.

🦀

There are 2 different ways to compile rust programs.

Rustc

The 1st using the compiler rustc. So starting from a classic hello.rs:

fn main() {
    println!("Hello, world!");
}

To compile our function:

$ rustc hello.rs

This will create a binary called hello, that will print the string Hello, World!.

Cargo

The 2nd using the package manager cargo. So running:

$ cargo new hello_world

we can create our first rust package and have a structure like the following:

$ cd hello_world
$ tree .
.
├── Cargo.toml
└── src
    └── main.rs

1 directory, 2 files

To interact with this package there are several options:

$ cargo check # To check if it is error-proof
$ cargo build # To compile it and store the binary under target/debug
$ cargo build --release # To compile it and store the binary under target/release
$ cargo run # To run the binary
$ cargo update # To update the version of all the dependencies
