Go-包含切片的接口不会编译

Question

type MyType interface {
    MyStringSlice []string
}

What is wrong with this?

It works well as a struct as in:

type MyType struct {
    MyStringSlice []string
}

but compiles with the following error when set as interface:

syntax error: unexpected [, expecting (

Answer 1

An interface can only hold methods or other interfaces. Have a look at the Language Specification.
