golang结构体是否实现了这个interface-可用demo与报错详情

demo

package main

import "fmt"

type a interface {
	show()
}

type p struct {
	name string
}

func (p1 * p)show1()  {
	fmt.Println("show name : "+p1.name)
}

// 语法： var _ 目标接口 = new(判断结构体)

var _ a = new(p)

func main()  {
    
}

如果未实现报错如下

# command-line-arguments
./main.go:17:5: cannot use new(p) (type *p) as type a in assignment:
        *p does not implement a (missing show method)
