### 各种nil判断
|
|||
|
|
- 切片定义但不初始化，则为nil
|
|||
|
|
```go
|
|||
|
|
func main() {
|
|||
|
|
var s []int
|
|||
|
|
fmt.Println(s == nil)
|
|||
|
|
}
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
- map定义但是不进行初始化，则为nil
|
|||
|
|
```go
|
|||
|
|
func main() {
|
|||
|
|
var m map[string]int
|
|||
|
|
fmt.Println(m == nil)
|
|||
|
|
}
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
- 接口变量定义但是不赋初值
|
|||
|
|
```go
|
|||
|
|
type MyInterface interface {
|
|||
|
|
M1(string)
|
|||
|
|
}
|
|||
|
|
|
|||
|
|
func main() {
|
|||
|
|
var m MyInterface
|
|||
|
|
fmt.Println(m == nil)
|
|||
|
|
}
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
- channel定义但是不初始化
|
|||
|
|
```go
|
|||
|
|
func main() {
|
|||
|
|
var ch chan int
|
|||
|
|
fmt.Println(ch == nil)
|
|||
|
|
}
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
- 指针类型变量没有被显式赋予初值
|
|||
|
|
```go
|
|||
|
|
type Book struct{}
|
|||
|
|
|
|||
|
|
func main() {
|
|||
|
|
var b *Book
|
|||
|
|
fmt.Println(b == nil)
|
|||
|
|
}
|
|||
|
|
```
