设置系统环境变量，如下设置RUSTUP_DIST_SERVER，其余同理

C:\Windows\System32>setx RUSTUP_DIST_SERVER http://mirrors.ustc.edu.cn/rust-static

成功: 指定的值已得到保存。

setx RUSTUP_DIST_SERVER http://mirrors.ustc.edu.cn/rust-static
setx RUSTUP_UPDATE_ROOT http://mirrors.ustc.edu.cn/rust-static/rustup
setx RUSTUP_HOME C:\Rust\Rustup
setx CARGO_HOME C:\Rust\Cargo

【以管理员身份运行】重新打开CMD，用set命令查看环境变量配置情况。

C:\Windows\System32>set
...
CARGO_HOME=C:\Rust\Cargo
...
RUSTUP_DIST_SERVER=http://mirrors.ustc.edu.cn/rust-static
RUSTUP_HOME=C:\Rust\Rustup
RUSTUP_UPDATE_ROOT=http://mirrors.ustc.edu.cn/rust-static/rustup
...

新建文件"C:\Rust\Cargo\config"，config无需后缀

config文件内容如下

[source.crates-io]
registry = "https://github.com/rust-lang/crates.io-index"
# 指定镜像
replace-with = 'ustc' # 如：tuna、sjtu、ustc，或者 rustcc
# 注：以下源配置一个即可，无需全部

Rust Visual C++ prerequisites

Rust requires a linker and Windows API libraries but they don't seem to be
available.

These components can be acquired through a Visual Studio installer.

1) Quick install via the Visual Studio Community installer
   (free for individuals, academic uses, and open source).

2) Manually install the prerequisites
   (for enterprise and advanced users).

3) Don't install the prerequisites
   (if you're targeting the GNU ABI).

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:\Rust\Rustup

This can be modified with the RUSTUP_HOME environment variable.

The Cargo home directory is located at:

  C:\Rust\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:\Rust\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:


   default host triple: x86_64-pc-windows-msvc
     default toolchain: stable (default)
               profile: default
  modify PATH variable: yes

1) Proceed with standard installation (default - just press enter)
2) Customize installation
3) Cancel installation

Rust is installed now. Great!

To get started you may need to restart your current shell.
This would reload its PATH environment variable to include
Cargo's bin directory (C:\Rust\Cargo\bin).

Press the Enter key to continue.

验证安装

安装完成，文件夹“C:\Rust\Rustup”和“C:\Rust\Cargo”新增很多文件。CMD运行：

C:\Users\sywq6>rustc -V
rustc 1.78.0 (9b00956e5 2024-04-29)

fn main() { 
    let number = 3; 
 
    if number < 5 { 
        println!("condition was true"); 
    } else { 
        println!("condition was false"); 
    }
