Golang 结构体初始化

有一个像这样的简单结构：

type Event struct {
    Id         int
    Name       string
}

这两种初始化方法有什么区别呢？

e1 := Event{Id: 1, Name: "event 1"}
e2 := &Event{Id: 2, Name: "event 2"}

为什么我要使用这两种初始化方法？

第一种方法

e1 := Event{Id: 1, Name: "event 1"}

正在初始化变量e1作为具有类型的值Event.

第二

e2 := &Event{Id: 1, Name: "event1"}

is initializing e2 as a pointer to a value of type Event As you stated in the comments, the set of methods defined on a value of a given type are a subset of the set of methods defined on a pointer to a value of that type. This means that if you have a method

func (e Event) GetName() string {
    return e.Name
}

然后两个e1 and e2可以调用此方法，但如果您有其他方法，请说：

func (e *Event) ChangeName(s string) {
    e.Name = s
}

Then e1无法使用ChangeName方法，同时e2 is.
