  • Cargo, Rust’s Package Manager

    http://doc.crates.io/

    Installing

    The easiest way to get Cargo is to get the current stable release of Rust by using the rustup script:

    $ curl -sSf https://static.rust-lang.org/rustup.sh | sh
    

    This will get you the current stable release of Rust for your platform along with the latest Cargo.

    If you are on Windows, you can directly download the latest 32bit (Rust and Cargo) or 64bit (Rust andCargo) Rust stable releases or Cargo nightlies.

    Alternatively, you can build Cargo from source.

    Let’s get started

    To start a new project with Cargo, use cargo new:

    $ cargo new hello_world --bin
    

    We’re passing --bin because we’re making a binary program: if we were making a library, we’d leave it off.

    Let’s check out what Cargo has generated for us:

    $ cd hello_world
    $ tree .
    .
    ├── Cargo.toml
    └── src
        └── main.rs
    
    1 directory, 2 files
    

    This is all we need to get started. First, let’s check out Cargo.toml:

    [package]
    name = "hello_world"
    version = "0.1.0"
    authors = ["Your Name <you@example.com>"]
    

    This is called a manifest, and it contains all of the metadata that Cargo needs to compile your project.

    Here’s what’s in src/main.rs:

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

    Cargo generated a “hello world” for us. Let’s compile it:

    $ cargo build
       Compiling hello_world v0.1.0 (file:///path/to/project/hello_world)

    And then run it:

    $ ./target/debug/hello_world
    Hello, world!
    

    We can also use cargo run to compile and then run it, all in one step:

    $ cargo run
         Fresh hello_world v0.1.0 (file:///path/to/project/hello_world)
       Running `target/hello_world`
    Hello, world!
