在serverHTTP中但在我的代码中没有错误，为什么？

Question

First code: http://play.golang.org/p/OEDetydMbW

Second code: http://play.golang.org/p/QZIrWALAm_

Can somebody explain me why I am not getting error on First code, I was expecting to error out stating missing CreateTable method.

Answer 1

You specify an interface Abc with the method CreateTable but none of your variable are actually of type interface Abc This slightly modified version will bring the error you seek: http://play.golang.org/p/ETdexzPYaM

package main

import "log"

// Abc asdlkfjaslf as
type Abc interface {
    CreateTable(a, b)
}

type a int
type b int

// Def klajsdlfkjaslfd
type Def int

// // CreateTable laksjdfljasfdl
// func (d *Def) CreateTable() {
//  log.Println("inside Def CreateTable....")
// }

func main() {
    var m1 Abc = Def(5)
    log.Println("inside main %d", m1)
}
