一、参考

emacs 系列文章目录——更新 ing

emacs rust-mode

Configuring Emacs for Rust development

My Emacs Rust Language Config

二、心愿实现的个性

个性 形容
源码之间挪动 找到函数的源码为止,回到函数援用处
代码主动填充
代码语法检查和谬误高亮
代码语法规范化
cargo 编译和运行

三、通过 emacs-racer 实现

3.1 依赖装置

程序 装置
rust 非 emacs 包
cargo 非 emacs 包
rust-mode M-x package-install rust-mode
cargo M-x package-install cargo
racer 非 emacs 包
rustup toolchain add nightly
rustup component add rust-src
cargo +nightly install racer
