在学习Rust 语言之前，先配置号本地Rust 语言环境
 
官网地址:https://rust-lang.org/zh-CN/
 
windows下载64位：
windows 根据cpu 下载intel 或者arm 的。我这里使用intel。
下载后直接安装：
首先会安装 Vistual Stall C++ 相关扩展。
会自动再次安装 rust 相关软件

ubuntu：安装，使用中科大最稳定
# 安装命令
export RUSTUP_DIST_SERVER=https://mirrors.ustc.edu.cn/rust-static
export RUSTUP_UPDATE_ROOT=https://mirrors.ustc.edu.cn/rust-static/rustup
curl --proto '=https' --tlsv1.2 -sSf https://mirrors.ustc.edu.cn/rust-static/rustup/rustup-init.sh | sh
# 命令结束，以下是提示
You can uninstall at any time with rustup self uninstall and
these changes will be reverted.

Current installation options:


   default host triple: x86_64-unknown-linux-gnu
     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
# 我默认选择 1 然后按回车。
1
# 等到，表示安装成功
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, you need to source
the corresponding env file under $HOME/.cargo.

This is usually done by running one of the following (note the leading DOT):
. "$HOME/.cargo/env"            # For sh/bash/zsh/ash/dash/pdksh 我用的zsh
source "$HOME/.cargo/env.fish"  # For fish
source "~/.cargo/env.nu"  # For nushell
source "$HOME/.cargo/env.tcsh"  # For tcsh
. "$HOME/.cargo/env.ps1"        # For pwsh
source "$HOME/.cargo/env.xsh"   # For xonsh

#我用zsh 运行 ，启动环境。
. "$HOME/.cargo/env"
