如何在Golang中初始化嵌套结构数组？ [重复]

Similar to this question, I'm try to initialize the following structure with some default values:

type Configuration struct {
    Val   string
    Proxy []struct {
        Address string
        Port    string
    }
}

Is there a way to do this without declaring Proxy separately?

You can initialize it as such

cfg := Configuration{
    Val: "foo",
    Proxy: []struct {
        Address string
        Port    string
    }{
        {Address: "a", Port: "093"},
    },
}

Yes, but since you have to declare the type somewhere, it gets (subjectively) ugly:

c := Configuration{
    Val: "value",
    Proxy: []struct {
        Address string
        Port    string
    }{
        {"addr1", "2"},
        {"addr2", "4"},
    },
}
