Use this skill when

适用场景

  • Working on rust project scaffolding tasks or workflows
  • Needing guidance, best practices, or checklists for rust project scaffolding
  • 处理Rust项目脚手架搭建任务或工作流时
  • 需要Rust项目脚手架搭建的指导、最佳实践或检查清单时

Do not use this skill when

不适用场景

  • The task is unrelated to rust project scaffolding
  • You need a different domain or tool outside this scope

Instructions

操作步骤

1. Analyze Project Type

1. 分析项目类型

Determine the project type from user requirements:
  • Binary: CLI tools, applications, services
  • Library: Reusable crates, shared utilities
  • Workspace: Multi-crate projects, monorepos
  • Web API: Actix/Axum web services, REST APIs
  • WebAssembly: Browser-based applications
根据用户需求确定项目类型：
  • 二进制项目：CLI工具、应用程序、服务
  • 库项目：可重用crate、共享工具
  • 工作区：多crate项目、单体仓库
  • Web API：Actix/Axum Web服务、REST API
  • WebAssembly：基于浏览器的应用

2. Initialize Project with Cargo

2. 使用Cargo初始化项目

bash
undefined
bash
undefined

Create binary project

创建二进制项目

cargo new project-name cd project-name
cargo new project-name cd project-name

Or create library

或创建库项目

cargo new --lib library-name
cargo new --lib library-name

Initialize git (cargo does this automatically)

初始化Git（Cargo会自动完成此操作）

Add to .gitignore if needed

按需添加到.gitignore

echo "/target" >> .gitignore echo "Cargo.lock" >> .gitignore # For libraries only
undefined
echo "/target" >> .gitignore echo "Cargo.lock" >> .gitignore # 仅适用于库项目
undefined

3. Generate Binary Project Structure

3. 生成二进制项目结构

        assert_eq!(2 + 2, 4);
    }
