结构体的字面值赋值问题（指针类型）-刚入门新手

1. 运行环境

//: go version go1.17 darwin/amd64

2. 问题描述？

//:
allProducts 切片的元素是 common.Product的指针类型，理论上 是一个指针，也就是内存地址， 为什么可以直接 赋值 common.Product结构体的字面值？
common包的结构体

    type Product struct {
        Id            int
        Name          string
        Size          int     
        Sale          int    
        ShipAddress   string 
        Price         float64 
        PositiveRatio float64 /
        RatioCount    int     
    }

实例化

allProducts := []*common.Product{
{Id: 1, Name: "小勺", Size: 35, Sale: 3582, ShipAddress: "郑州", Price: 6.9, PositiveRatio: 0.76, RatioCount: 364},
{Id: 2, Name: "袜子", Size: 23, Sale: 43654, ShipAddress: "郑州", Price: 6546, PositiveRatio: 0.86, RatioCount: 7},
{Id: 3, Name: "裤子", Size: 354, Sale: 54, ShipAddress: "郑州", Price: 547, PositiveRatio: 0.96, RatioCount: 5436},

}
