emacs 支持rust的配置

注：

1、export PATH="$HOME/.cargo/bin:$PATH"加到文件.bashrc,

(exec-path-from-shell-initialize)加到emacs配置文件以解决:auto-save-buffer cant locate executable rustfmt；

2、(setq racer-rust-src-path "/home/wang/.rustup/toolchains/stable-x86_64-unknown-linux-gnu/lib/rustlib/src/rust/src")不能自动补全添加；

3、安装racer到此网站：https://github.com/racer-rust/emacs-racer；

4、如果找不到racer添加：(setq racer-cmd "~/.cargo/bin/racer")；
