话说前面: 如果你 之前安装过老版本的 rust 请先卸载 我说的是以 msi 文件安装的那种, 请进控制面板–> 程序中进行卸载 
首先 下载官网 的 rustup-init.exe 当前版本是 1.18.0 
然后下载完 然后点击 rusupt-init.exe 
奇迹发生了: 
 
选 2 进行自定义安装 会一步一步问你 第一个问你是否用 default host tripe 我选的是 
第二个会问你 用哪个版本 我输入 stable 
第三个会问你是否 默认修改环境变量 (这个无所谓了可以后期改) 我选是 
然后就会安装…

安装完成后你会发现在 c 盘–> 用户—->(你的登陆名下) 会多出两个文件夹. rustup 文件夹和. cargo 文件夹 
如果你不想将这两个文件夹放置在 c 盘下那么就把它们剪切到别的盘符下我是移动到了别的盘符了, 单单移动是不行的 
那么你还得 修改环境变量: 

CARGO_HOME = "%USERPROFILE%\.cargo"
RUSTUP_HOME = "%USERPROFILE%\.rustup"

接着添加中科大 rust 源: 
在. cargo 文件夹根目录下创建一个 config 文件 没有任何文件后缀, 内容为:

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

下载安装镜像时，你只需要把

https://static.rust-lang.org

换成 https://mirrors.ustc.edu.cn/rust-static 即可!

接着再添加环境变量:

RUSTUP_DIST_SERVER = "http://mirrors.ustc.edu.cn/rust-static"
RUSTUP_UPDATE_ROOT = "http://mirrors.ustc.edu.cn/rust-static/rustup"

将 cargo 加入 path 环境变量:

%CARGO_HOME%\bin

前期工作就可以了 那么打开 cmd 输入 
检查 rustup 有无安装成功

rustup -V

cargo -V

检查 cargo 安装 
如果 提示没有默认的 toolchain 那么 install:

rustup install stable-x86_64-pc-windows-msvc

将 msvc 版设为 default

rustup default stable-x86_64-pc-windows-msvc

如果设置成功 那么 console 会打印出正确的版本号 
安装插件: 
安装 rustfmt: 
首先 cmd 输入:

rustup show

查看 当前 toolchain, 初次安装应该只有 stable-msvc 
那么进行安装 stable-gnu

rustup install stable-x86_64-pc-windows-gnu
rustup install nightly-x86_64-pc-windows-msvc
rustup install nightly-x86_64-pc-windows-gnu

安装 rls-preview rust-analysis rust-src:

参考 https://github.com/rust-lang-nursery/rls
Note (nightly only)
Sometimes the rls-preview component is not included in a nightly build due to certain issues. To see if the component is included in a particular build and what to do if it's not, check #641.

rustup component add rls-preview rust-analysis rust-src --toolchain stable-x86_64-pc-windows-msvc
rustup component add rls-preview rust-analysis rust-src --toolchain stable-x86_64-pc-windows-gnu
rustup component add rust-analysis rust-src --toolchain nightly-x86_64-pc-windows-msvc
rustup component add rust-analysis rust-src --toolchain nightly-x86_64-pc-windows-gnu

安装 cargo-release:

cargo +stable-x86_64-pc-windows-msvc install cargo-release

安装 cargo-check:

cargo +stable-x86_64-pc-windows-msvc install cargo-check

安装 rustfmt:

cargo +stable-x86_64-pc-windows-msvc install rustfmt

安装 rustsym:

cargo +stable-x86_64-pc-windows-msvc install rustsym

安装 racer:

cargo +stable-x86_64-pc-windows-msvc install racer

设置 rust_src_path 环境变量（此环境变量不应该写死，在Linux中可以采用灵活的方式确定该变量值）

RUST_SRC_PATH = "%USERPROFILE%\.rustup\toolchains\stable-x86_64-pc-windows-msvc\lib\rustlib\src\rust\src"

参考 https://github.com/racer-rust/racer

Fetch the Rust sourcecode

automatically via rustup and run rustup component add rust-src in order to install the source to $(rustc --print sysroot)/lib/rustlib/src/rust/src. Rustup will keep the sources in sync with the toolchain if you run rustup update.

manually from git, or download from https://www.rust-lang.org/install.html (the 'rustc' source download behind the 'source' link is the right one).

Set the RUST_SRC_PATH environment variable to point to the 'src' dir in the Rust source installation

(e.g. % export RUST_SRC_PATH=/usr/local/src/rust/src or % export RUST_SRC_PATH="$(rustc --print sysroot)/lib/rustlib/src/rust/src" )

Test on the command line:

racer complete std::io::B (should show some completions)
