一、安装 Rust

官网安装教程：https://www.rust-lang.org/zh-CN/tools/install

用 rustup 管理工具链

Rust 由工具 rustup 安装和管理。Rust 有着以 6 星期为周期的快速版本迭代机制，支持大量平台，因而不同时期存在大量不同的 Rust 构建版本。 rustup 用于管理不同平台下的 Rust 构建版本并使其互相兼容，支持安装由 Beta 和 Nightly 频道发布的版本，并支持其他用于交叉编译的编译版本。

如果您曾经安装过 rustup，可以执行 rustup update 来升级 Rust。

对于大多数开发者而言，推荐用 rustup 来安装 Rust 。

Cargo：Rust 的构建工具和包管理器

Cargo：Rust 的构建工具和包管理器
您在安装 Rustup 时，也会安装 Rust 构建工具和包管理器的最新稳定版，即 Cargo。Cargo 可以做很多事情：

cargo build 可以构建项目
cargo run 可以运行项目
cargo test 可以测试项目
cargo doc 可以为项目构建文档
cargo publish 可以将库发布到 crates.io。
要检查您是否安装了 Rust 和 Cargo，可以在终端中运行：

cargo --version

cargo手册： https://doc.rust-lang.org/cargo/index.html

Windows中的Rust安装

在Windows上, 打开链接 https://www.rust-lang.org/zh-CN/tools/install 然后按照说明安装Rust。按照所有说明进行操作之后, Rust将被安装并显示屏幕：

Welcome to Rust!

This will download and install the official compiler for the Rust
programming language, and its package manager, Cargo.

Rustup metadata and toolchains will be installed into the Rustup
home directory, located at:

  C:\Users\intha\.rustup

This can be modified with the RUSTUP_HOME environment variable.

The Cargo home directory located at:

  C:\Users\intha\.cargo

This can be modified with the CARGO_HOME environment variable.

The cargo, rustc, rustup and other commands will be added to
Cargo's bin directory, located at:

  C:\Users\intha\.cargo\bin

This path will then be added to your PATH environment variable by
modifying the HKEY_CURRENT_USER/Environment/PATH registry key.

You can uninstall at any time with rustup self uninstall and
these changes will be reverted.

Current installation options:

Rust is installed now. Great!

To get started you need Cargo's bin directory (%USERPROFILE%\.cargo\bin) in
your PATH environment variable. Future applications will automatically
have the correct environment, but you may need to restart your current shell.

Press the Enter key to continue.

安装后, Rust的PATH变量会自动添加到你的系统PATH中。

打开命令提示符, 然后运行以下命令：

$ rustc --version

linux 中Rust安装

在Linux上安装Rust一般会很简单。按照官网（Install Rust）的说明，我们应该能够通过执行下面的命令来安装它。

curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh

但是，在国内，有时候，安装过程会很慢甚至不稳定。因此，我可能会需要配置toolchain和rustup更新服务器的镜像。（其中 RUSTUP_DIST_SERVER默认指向 https://static.rust-lang.org, RUSTUP_UPDATE_ROOT默认指向https://static.rust-lang.org/rustup）

# 用于更新 toolchain
export RUSTUP_DIST_SERVER=https://mirrors.ustc.edu.cn/rust-static
# 用于更新 rustup
export RUSTUP_UPDATE_ROOT=https://mirrors.ustc.edu.cn/rust-static/rustup

在国内我们还有可能需要配置http://crates.io的镜像。我们可以通过修改配置文件~/.cargo/config(如果不存在则需要手动创建）来配置镜像。

# ~/.cargo/config
[source.crates-io]
registry = "https://github.com/rust-lang/crates.io-index"
replace-with = 'ustc'
[source.ustc]
registry = "git://mirrors.ustc.edu.cn/crates.io-index"

home directory, located at:

  /root/.rustup

This can be modified with the RUSTUP_HOME environment variable.

Rust is installed now. Great!

To get started you may need to restart your current shell.
This would reload your PATH environment variable to include
Cargo's bin directory ($HOME/.cargo/bin).

To configure your current shell, run:
source $HOME/.cargo/env
root@aaa2:~# source $HOME/.cargo/env
root@aaa2:~# rustc -V
rustc 1.57.0 (f1edd0429 2021-11-29)

最后根据上面提醒，执行 source $HOME/.cargo/env

rust为我们提供一个脚步~/.cargo/env帮助我们把Cargon的bin目录写入环境变量PATH中 .

Rustup的根目录： ~/.rustup, 可以通过环境变量RUSTUP_HOME来修改
Cargo的根目录：~/.cargo, 可以通过环境变量CARGO_HOME来修改
Cargo的bin目录：~/.cargo/bin, 其中包含cargo, rustup等其他命令。该路径需要添加到环境变量PATH中。

二、VS Code 搭建 Rust 开发环境

打开 vs code 找到插件工具栏，单击打开并在搜索栏输入 “rust” 搜索 Rust 插件

rustdesk 手机端掉后台_Rust

Hello World

新建一个文件夹，然后用VS Code打开
2. 创建新项目
我们将在新的 Rust 开发环境中编写一个小应用。首先用 Cargo 创建一个新项目。在您的终端中执行：

cargo new hello-rust

这会生成一个名为 hello-rust 的新目录，其中包含以下文件：

hello-rust
|- Cargo.toml
|- src
  |- main.rs

Cargo.toml 为 Rust 的清单文件。其中包含了项目的元数据和依赖库。
src/main.rs 为编写应用代码的地方。

cargo new 会生成一个新的“Hello, world!”项目！我们可以进入新创建的目录中，执行下面的命令来运行此程序：

cargo run

您应该会在终端中看到如下内容：

PS E:\code\rust-test\hello-rust> cargo run
   Compiling hello-rust v0.1.0 (E:\code\rust-test\hello-rust)
    Finished dev [unoptimized + debuginfo] target(s) in 3.29s
     Running `target\debug\hello-rust.exe`
Hello, world!
PS E:\code\rust-test\hello-rust>
