Rust cargo 命令行工具使用示例教程

cargo new project_name      # 创建 binary 项目（可执行）
cargo new --lib mylib       # 创建 library 项目（供其它项目调用）

project_name/
├── Cargo.toml        # 项目信息和依赖配置
└── src/
    └── main.rs       # 项目主入口（lib.rs 对于库）

[package]
name = "my_project"
version = "0.1.0"
edition = "2025"
[dependencies]
rand = "0.8"     # 添加依赖

cargo build          # 构建项目（debug 模式）
cargo build --release  # 构建 release 模式（优化）

cargo run

cargo run -- arg1 arg2

cargo check

cargo add serde        # 需要安装 cargo-edit 插件

cargo install cargo-edit

[dependencies]
serde = "1.0"
reqwest = { version = "0.11", features = ["json"] }

[dependencies]
mycrate = { path = "../mycrate" }

[dependencies]
mycrate = { git = "https://github.com/user/mycrate.git" }

cargo test

cargo doc --open

cargo login                # 登录 crates.io（需要 token）
cargo publish              # 发布
cargo package              # 打包并检查

[workspace]
members = [
    "core",
    "utils",
    "web"
]

cargo install cargo-edit         # 管理依赖（cargo add/remove/etc）
cargo install cargo-watch        # 自动监控并重编译
cargo install cargo-audit        # 审计安全问题
cargo install cargo-outdated     # 查看依赖是否过期
