You favor small, composable interfaces and concrete return types ā€” you design for testability and clarity, not for abstraction's sake.\n\n> **Community default.** A company skill that explicitly supersedes `samber/cc-skills-golang@golang-structs-interfaces` skill takes precedence.\n\n# Go Structs & Interfaces\n\n## Interface Design Principles\n\n### Keep Interfaces Small\n\n> \"The bigger the interface, the weaker the abstraction.\" ā€” Go Proverbs\n\nInterfaces SHOULD have 1-3 methods. Small interfaces are easier to implement, mock, and compose. If you need a larger contract, compose it from small interfaces:\n\nā†’ See `samber/cc-skills-golang@golang-naming` skill for interface naming conventions (method + \"-er\" suffix, canonical names)\n\n```go\ntype Reader interface {\n Read(p []byte) (n int, err error)\n}\n\ntype Writer interface {\n Write(p []byte) (n int, err error)\n}\n\n// Composed from small interfaces\ntype ReadWriter interface {\n Reader\n Writer\n}\n```\n\nCompose larger interfaces from smaller ones:\n\n```go\ntype ReadWriteCloser interface {\n io.Reader\n io.Writer\n io.Closer\n}\n```\n\n### Define Interfaces Where They're Consumed\n\nInterfaces Belong to Consumers.\n\nInterfaces MUST be defined where consumed, not where implemented. This keeps the consumer in control of the contract and avoids importing a package just for its interface.\n\n```go\n// package notification ā€” defines only what it needs\ntype Sender interface {\n Send(to, body string) error\n}\n\ntype Service struct {\n sender Sender\n}\n```\n\nThe `email` package exports a concrete `Client` struct ā€” it doesn't need to know about `Sender`.\n\n### Accept Interfaces, Return Structs\n\nFunctions SHOULD accept interface parameters for flexibility and return concrete types for clarity. Callers get full access to the returned type's fields and methods; consumers upstream can still assign the result to an interface variable if needed.\n\n```go\n// Good ā€” accepts interface, returns concrete\nfunc NewService(store UserStore) *Service { ... }\n\n// Bad ā€” an interface return hides every other method of the concrete type from callers\nfunc NewService(store UserStore) ServiceInterface { ... }\n```\n\n### Don't Create Interfaces Prematurely\n\n> \"Don't design with interfaces, discover them.\"\n\nAn interface written before a second implementation exists is a guess about which methods will vary ā€” and the guess is usually wrong, so the abstraction has to be reshaped anyway. Meanwhile it costs a layer of indirection that hides the concrete type from readers and tooling. Start with concrete types; extract an interface once a second consumer, a second implementation, or a test mock demands it.\n\n```go\n// Bad ā€” premature interface with a single implementation\ntype UserRepository interface {\n FindByID(ctx context.Context, id string) (*User, error)\n}\ntype userRepository struct { db *sql.DB }\n\n// Good ā€” start concrete, extract an interface later when needed\ntype UserRepository struct { db *sql.DB }\n```\n\n## Make the Zero Value Useful\n\nDesign structs so they work without explicit initialization. A well-designed zero value reduces constructor boilerplate and prevents nil-related bugs:\n\n```go\n// Good ā€” zero value is ready to use\nvar buf bytes.Buffer\nbuf.WriteString(\"hello\")\n\nvar mu sync.Mutex\nmu.Lock()\n\n// Bad ā€” zero value is broken, requires constructor\ntype Registry struct {\n items map[string]Item // nil map, panics on write\n}\n\n// Good ā€” lazy initialization guards the zero value\nfunc (r *Registry) Register(name string, item Item) {\n if r.items == nil {\n r.items = make(map[string]Item)\n }\n r.items[name] = item\n}\n```\n\n## Avoid `any` / `interface{}` When a Specific Type Will Do\n\nSince Go 1.18+, MUST prefer generics over `any` for type-safe operations. Use `any` only at true boundaries where the type is genuinely unknown (e.g., JSON decoding, reflection):\n\n```go\n// Bad ā€” loses type safety\nfunc Contains(slice []any, target any) bool { ... }\n\n// Good ā€” generic, type-safe\nfunc Contains[T comparable](slice []T, target T) bool { ... }\n```\n\n## Key Standard Library Interfaces\n\n| Interface | Package | Method |\n| ------------- | --------------- | ------------------------------------- |\n| `Reader` | `io` | `Read(p []byte) (n int, err error)` |\n| `Writer` | `io` | `Write(p []byte) (n int, err error)` |\n| `Closer` | `io` | `Close() error` |\n| `Stringer` | `fmt` | `String() string` |\n| `error` | builtin | `Error() string` |\n| `Handler` | `net/http` | `ServeHTTP(ResponseWriter, *Request)` |\n| `Marshaler` | `encoding/json` | `MarshalJSON() ([]byte, error)` |\n| `Unmarshaler` | `encoding/json` | `UnmarshalJSON([]byte) error` |\n\nCanonical method signatures MUST be honored ā€” if your type has a `String()` method, it must match `fmt.Stringer`. Don't invent `ToString()` or `ReadData()`.\n\n## Compile-Time Interface Check\n\nVerify a type implements an interface at compile time with a blank identifier assignment. Place it near the type definition:\n\n```go\nvar _ io.ReadWriter = (*MyBuffer)(nil)\n```\n\nThis costs nothing at runtime. If `MyBuffer` ever stops satisfying `io.ReadWriter`, the build fails immediately.\n\n## Type Assertions & Type Switches\n\nType assertions MUST use the comma-ok form (`s, ok := val.(string)`) ā€” the single-value form panics on a type mismatch instead of branching. Use a type switch to dispatch on the dynamic type, and an assertion to a small optional interface (`if f, ok := w.(Flusher); ok`) to exploit richer implementations without widening the declared parameter type.\n\nā†’ See [Type Assertions & Type Switches](references/type-assertions.md) for type switch ordering, nil cases, and the optional-behavior pattern.\n\n## Struct & Interface Embedding\n\n### Struct Embedding\n\nEmbedding promotes the inner type's methods and fields to the outer type ā€” composition, not inheritance:\n\n```go\ntype Logger struct {\n *slog.Logger\n}\n\ntype Server struct {\n Logger\n addr string\n}\n\n// s.Info(...) works ā€” promoted from slog.Logger through Logger\ns := Server{Logger: Logger{slog.Default()}, addr: \":8080\"}\ns.Info(\"starting\", \"addr\", s.addr)\n```\n\nThe receiver of promoted methods is the _inner_ type, not the outer. The outer type can override by defining its own method with the same name.\n\n### When to Embed vs Named Field\n\n| Use | When |\n| --- | --- |\n| **Embed** | You want to promote the full API of the inner type ā€” the outer type \"is a\" enhanced version |\n| **Named field** | You only need the inner type internally ā€” the outer type \"has a\" dependency |\n\n```go\n// Embed ā€” Server exposes all http.Handler methods\ntype Server struct {\n http.Handler\n}\n\n// Named field ā€” Server uses the store but doesn't expose its methods\ntype Server struct {\n store *DataStore\n}\n```\n\n## Dependency Injection via Interfaces\n\nAccept dependencies as interfaces in constructors. This decouples components and makes testing straightforward:\n\n```go\ntype UserStore interface {\n FindByID(ctx context.Context, id string) (*User, error)\n}\n\ntype UserService struct {\n store UserStore\n}\n\nfunc NewUserService(store UserStore) *UserService {\n return &UserService{store: store}\n}\n```\n\nIn tests, pass a mock or stub that satisfies `UserStore` ā€” no real database needed.\n\n## Struct Field Tags\n\nExported fields in serialized structs MUST have field tags ā€” without one, the encoder falls back to the Go field name, so renaming a field silently changes the wire format:\n\n```go\ntype Order struct {\n ID string `json:\"id\" db:\"id\"`\n Total float64 `json:\"total\" db:\"total\"`\n CreatedAt time.Time `json:\"created_at\" db:\"created_at\"`\n Internal string `json:\"-\" db:\"-\"`\n}\n```\n\nā†’ See [Struct Fields: Tags and Copy Safety](references/struct-fields.md) for the full tag directive table, the `omitempty` vs `omitzero` trap, and `go vet` diagnostics.\n\n## Pointer vs Value Receivers\n\n| Use pointer `(s *Server)` | Use value `(s Server)` |\n| --- | --- |\n| Method modifies the receiver | Receiver is small and immutable |\n| Receiver contains `sync.Mutex` or similar | Receiver is a basic type (int, string) |\n| Receiver is a large struct | Method is a read-only accessor |\n| Consistency: if any method uses a pointer, all should | Map and function values (already reference types) |\n\nReceiver type MUST be consistent across all methods of a type ā€” if one method uses a pointer receiver, all methods should.\n\n## Preventing Struct Copies with `noCopy`\n\nA struct holding a mutex, a channel, or internal pointers breaks when copied: the copy duplicates the lock state, so two goroutines guard two different mutexes and the invariant disappears silently. Embed a `noCopy` sentinel so `go vet` reports every value copy, and pass such structs by pointer.\n\n**Diagnose:** 1- `go vet ./...` ā€” `copylocks` reports value copies of lock-bearing structs\n\nā†’ See [Struct Fields: Tags and Copy Safety](references/struct-fields.md) for the `noCopy` implementation and how `vet` detects it.\n\n## Cross-References\n\n- ā†’ See `samber/cc-skills-golang@golang-naming` skill for interface naming conventions (Reader, Closer, Stringer)\n- ā†’ See `samber/cc-skills-golang@golang-design-patterns` skill for functional options, constructors, and builder patterns\n- ā†’ See `samber/cc-skills-golang@golang-dependency-injection` skill for DI patterns using interfaces\n- ā†’ See `samber/cc-skills-golang@golang-code-style` skill for value vs pointer function parameters (distinct from receivers)\n- ā†’ See `samber/cc-skills-golang@golang-gopls` skill for safe rename and the `implementInterface` code action ā€” renaming a method or receiver that participates in interface satisfaction updates every call site and refuses a rename that would silently break the interface, which grep/sed cannot detect\n\n## Common Mistakes\n\n| Mistake | Fix |\n| --- | --- |\n| Large interfaces (5+ methods) | Split into focused 1-3 method interfaces, compose if needed |\n| Defining interfaces in the implementor package | Define where consumed |\n| Returning interfaces from constructors | Return concrete types |\n| Bare type assertions without comma-ok | Always use `v, ok := x.(T)` |\n| Embedding when you only need a few methods | Use a named field and delegate explicitly |\n| Missing field tags on serialized structs | Tag all exported fields in marshaled types |\n| Mixing pointer and value receivers on a type | Pick one and be consistent |\n| Forgetting compile-time interface check | Add `var _ Interface = (*Type)(nil)` |\n| Using `ToString()` instead of `String()` | Honor canonical method names |\n| Premature interface with a single implementation | Start concrete, extract interface when needed |\n| Nil map/slice in zero value struct | Use lazy initializatio","tagline":"Golang struct and interface design patterns ā€” composition, embedding, type assertions, type switches, interface segregation, dependency injection via interfaces, struct field tags, and pointer vs value receivers.
