Golang Structural Body

This is a creation in Article, where the information may have evolved or changed.

First, struct declaration and initialization:

/*声明结构体*/type person struct {    name string    age  int}/*初始化结构体，并赋给变量 per*/per ：= person {name : "eagle", age : 24}

Ii. Anonymous struct declaration and initialization

per := struct {    name string    age  int}{    name : "eagle", age : 24,}/*备注：  (1) 匿名结构体的初始化和声明必须合并，不能拆分开  (2) 这里的最后一个逗号（,）必须要有，否则会报错*/

Third, struct anonymous member declaration and initialization

/*声明结构体*/type person struct{    string    int}/*初始化结构体，并赋给变量 per*/per ：= person {name : "eagle", age : 24}/*备注：结构体内部限制成员类型不能相同，即type person struct{    string    int}per ：= person {"eagle", “guangdong", 24}会抛出“duplicate field string”异常信息，GO语言系统不会聪明地认为第一个成员和第二个成员都是string类型，第三个成员是int类型*/

Iv. structure Nesting

/*声明结构体*/type person struct {    name string    age  int}type man struct {    sex  string    person}/*初始化结构体，并赋给变量 man*/man ：= person {sex : "男", person : person {name : "eagle", age : 24}}

V. Structural methods

import "fmt"/*声明结构体*/type person struct{    name string    age  int}/*判断两个人是否名字相同，值传递，返回值为 bool*/func (per person) IsEqual(anoPer person) bool {    anoPer.name = "john"    return per.name == anoPer.name}/*交换两个人名字，引用传递，无返回值*/func swap(per* person, anoPer* person) {    anoPer.name, per.name = per.name, anoPer.name}func main() {/*初始化结构体，并赋给变量 per*/perOne := person {name : "eagle", age : 24}perTwo := person {name : "john", age : 24}fmt.Println("PerOne：" + perOne.name)swap(&perOne, &perTwo)fmt.Println("PerOne：" + perOne.name)}
