英文:
about golang type create Specification
问题
示例代码：
package main
import "fmt"
type ipoint int
type Futest struct {
Name string
}
func main() {
i := ipoint(1)
fmt.Println(i) //打印 1
futest := Futest{
Name: "test",
}
fmt.Println(futest) //打印 {test}
}
我的问题是：为什么ipoint对象只需要ipoint(1)来创建，而Futest结构需要更复杂的语句
Futest{
Name: "test",
}
是否有golang规范描述它？
英文:
the example code
package main
import "fmt"
type ipoint int
type Futest struct {
Name string
}
func main() {
i := ipoint(1)
fmt.Println(i) //print 1
futest := Futest{
Name: "test",
}
fmt.Println(futest) //print {test}
}
my question is :
why ipoint object only ipoint(1) create,but Futest struct need more complex statmenet
Futest{
Name: "test",
}
答案1
得分: 2
ipoint是一种int类型，Futest是一种struct类型。我们可以将整数转换为ipoint并赋值给一个名为i的新变量，如下所示。
i := ipoint(1)
我们可以按如下所示从struct创建一个新实例。
futest := Futest{
Name: "test",
}
// 或者
futest := Futest{"test"}
// 如果struct有多个字段，
// 我们需要保持字段的顺序。
//
// 例如：
//
// type A struct {
// Number int
// Name string
// }
//
// a := A{1,"sample"}
英文:
ipoint is a type of int and Futest is a type of struct. We can covert integer to ipoint and assign to new variable called i as shown below.
i := ipoint(1)
We can create a new instance from struct as shown below.
futest := Futest{
Name: "test",
}
// or
futest := Futest{"test"}
// If the struct has more than one fields,
// We need to maintain the order of fields.
//
// Example:
//
// type A struct {
// Number int
// Name string
// }
//
// a := A{1,"sample"}
