//go install github.com/abice/go-enum@latest
//go:generate go-enum --output-suffix _generate.go
//swag i --pd --output ./docs/api --v3.1

// ENUM(a,b,c,d)
type EC string

type Response[t any] struct {
	EC    EC     `json:"ec"`
	Data  t      `json:"data"`
	Error string `json:"error"`
}

// ENUM(aa,bb,cc,dd)
type OtherEnum string

type Complex struct {
	F1 EC          `json:"f_1"`
	F2 []OtherEnum `json:"f_2"`
	F3 []int       `json:"f_3"`
}

// @contact.name   API Support
func main() {
	r := gin.New()
	r.Run()
}

// @Summary      test1
// @Description  test1
// @Produce      json
// @Success      200  {object}  Response[string]
// @Router       /test1 [get]
func test1() {}

// @Summary      test2
// @Description  test2
// @Produce      json
// @Success      200  {object}  Response[[]Complex]
// @Router       /test2 [get]
func test2() {}

this with result

    main.Response-array_main_Complex:
      properties:
        data:
          items:
            $ref: '#/components/schemas/main.Complex'
          type: array
          uniqueItems: false
        ec:
          type: string
