# Go 模式(Go Patterns)

> 本文件扩展了通用模式规则,包含了 Go 特有的内容。

## 函数式选项(Functional Options)

```go
type Option func(*Server)

func WithPort(port int) Option {
    return func(s *Server) { s.port = port }
}

func NewServer(opts ...Option) *Server {
    s := &Server{port: 8080}
    for _, opt := range opts {
        opt(s)
    }
    return s
}
```

## 小接口(Small Interfaces)

在接口被使用的地方定义它们,而不是在实现它们的地方定义。

## 依赖注入(Dependency Injection)

使用构造函数(Constructor functions)来注入依赖:

```go
func NewUserService(repo UserRepository, logger Logger) *UserService {
    return &UserService{repo: repo, logger: logger}
}
```

## 参考(Reference)

请参阅技能(Skill):`golang-patterns` 以获取全面的 Go 模式,包括并发、错误处理和包组织。
