Cargo 配置

自动补全

默认情况下, cargo 命令并不会补全输入的子命令, 但是 Rust 工具链提供了 bash 补全 配置脚本, 我们只需要引入它即可. 以 nightly 版本为例, 可以在 ~/.bashrc 文件中 加入以下内容:

if [ -f ~/.rustup/toolchains/nightly-x86_64-unknown-linux-gnu/etc/bash_completion.d/cargo ]; then
  source ~/.rustup/toolchains/nightly-x86_64-unknown-linux-gnu/etc/bash_completion.d/cargo
fi

编译相关的常用配置

[profile.bench]
opt-level = 3
debug = false
rpath = false
lto = true
debug-assertions = false
codegen-units = 1

[profile.release]
opt-level = 3
debug = false
rpath = false
lto = true
debug-assertions = false
codegen-units = 1
