Extend Go struct capabilities
There are various approaches to reduce Go boilerplate like go generate and others. Traits library comes to add capabilities and reduce boilerplate using embedded structs.
Traits list:
- traits.Hash - struct unique hash generators
- traits.Jsonify - marshal struct to JSON
- traits.Stringify - stringify struct
- traits.Validator - validate struct fields
Hooks interfaces:
- traits.bootstrap - triggered on traits.Init()
- traits.finalize - sets object finalizer via
runtime.SetFinalizer(ptr, finalizerFunc)
type Inner struct {
Arr []bool
}
type Test struct {
traits.Hash
traits.Jsonify
traits.Stringify
traits.Validator
Num int `json:"num"`
Str string `json:"str" valid:"numeric"`
Inn Inner
}
func (t *Test) Bootstrap() {
fmt.Println("Bootstrap Test struct...")
}
func (t *Test) Finalize() {
fmt.Println("Finalize Test struct...")
}
func main() {
obj := Test{Num: 1, Str: "abc", Inn: Inner{make([]bool, 2)}}
traits.Init(&obj)
fmt.Println(obj.ToString())
fmt.Println(obj.ToJSON())
fmt.Println(obj.Md5Hex())
fmt.Println(obj.Sha256Hex())
fmt.Println(obj.Validate())
}See examples folder for more.
Feel free to add more capabilities
