一、环境

二、安装

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

Welcome to Rust.

This script will download the Rust compiler and its package manager, Cargo, and
install them to /usr/local. You may install elsewhere by running this script
with the --prefix=<path> option. The installer will run under 'sudo' and may ask you for your password. If you do
not want the script to run 'sudo' then pass it the --disable-sudo flag. You may uninstall later by running /usr/local/lib/rustlib/uninstall.sh,
or by running this script again with the --uninstall flag. Continue? (y/N) y rustup: gpg not available. signatures will not be verified

三、查看

$rustc --version

rustc 1.7.0 (a5d1e7a59 2016-02-29)

$cargo --version

cargo 0.8.0-nightly (28a0cbb 2016-01-17)
 

四、创建项目文件夹结构

$cd ~

$mkdir develop

$cd develop/

$mkdir rust-projects

$cd rust-projects/

$mkdir hello_world

$cd hello_world/

五、rust 之 helloworld

$vi main.rs

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

$rustc main.rs

$./main

Hello,world!
 

六、cargo 之 helloworld

当前文件夹在 hello_world

1、主要的cargo 命令行

$mkdir src

$mv main.rs src/main.rs

$rm main

$vi Cargo.toml

Cargo.toml的内容例如以下

[package]
name = "hello_world"
version = "0.0.1"
authors = ["teamlet@email.com"]

$cargo build

Compiling hello_world v0.0.1 (file:///Users/teamlet/develop/rust-projects/hello_world)
 

$./target/debug/hello_world

     Hello,world!
 

$cargo run

     Running `target/debug/hello_world`
Hello,world!

$cargo build --release

  Compiling hello_world v0.0.1 (file:///Users/teamlet/develop/rust-projects/hello_world)
 

$cat Cargo.lock

[root]
name = "hello_world"
version = "0.0.1"

2、cargo项目的管理工具

1) 自己主动生成项目

$cd ..

$mkdir cargo_test

$cd cargo_test/

$cargo new hello_world --bin

$cd hello_world/

$cat Cargo.toml //查看cargo自己主动生成的配置文件

[package]
name = "hello_world"
version = "0.1.0"
authors = ["teamlet <teamlet@mail.com>"] [dependencies]

$cd src/

$cat main.rs //查看cargo自己主动生成的helloworld代码

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

2)猜数游戏

$cd ..

$cargo new guessing_game --bin

$cd guessing_game/

$cargo build

   Compiling guessing_game v0.1.0 (file:///Users/teamlet/develop/rust-projects/guessing_game)
 

$cargo run

     Running `target/debug/guessing_game`
Hello, world!

$vi src/main.rs

use std::io;

fn main() {
println!("Guess the number!"); println!("Please input your guess."); let mut guess = String::new(); io::stdin().read_line(&mut guess)
.expect("Failed to read line"); println!("You guessed:{}",guess);
}

$cargo run

   Compiling guessing_game v0.1.0 (file:///Users/teamlet/develop/rust-projects/guessing_game)
Running `target/debug/guessing_game`
Guess the number!
Please input your guess.
5
You guessed:5

$vi Cargo.toml //添加 dependencies

[package]
name = "guessing_game"
version = "0.1.0"
authors = ["teamlet <teamlet@mail.com>"] [dependencies] rand = "^0.3.13"

$cargo build

    Updating registry `https://github.com/rust-lang/crates.io-index`
Downloading rand v0.3.13
Downloading winapi-build v0.1.1
Downloading advapi32-sys v0.1.2

假设出现 

unable to get packages from source

则须要多次重复运行 cargo build 或者 cargo build -verbose,直到

改动代码,生成随机数

$vi src/main.rs

extern crate rand;

use std::io;
use rand::Rng; fn main() {
println!("Guess the number!"); let secret_number = rand::thread_rng().gen_range(1, 101); println!("The secret number is: {}", secret_number); println!("Please input your guess."); let mut guess = String::new(); io::stdin().read_line(&mut guess)
.expect("failed to read line"); println!("You guessed: {}", guess);
}

$cargo build

Compiling guessing_game v0.1.0 (file:///Users/teamlet/develop/rust-projects/guessing_game)
 

$cargo run

     Running `target/debug/guessing_game`
Guess the number!
The secret number is: 55
Please input your guess.
