Go does not provide exceptions or structured error handling. Instead, it handles errors by returning them in a second or later return value:
|
Go 没有提供异常类或者结构化的错误处理。然而,它通过第二个及后续的返回值来返回错误从而处理错误:
|
||||||
|
|
||||||
```
|
```
|
||||||
func Read(p []byte) (n int, err error)
|
func Read(p []byte) (n int, err error)

// Built-in type:
|
// 内建类型:
|
||||||
type error interface {
|
type error interface {
|
||||||
Error() string
|
Error() string
|
||||||
}
|
}
|

```

```

Errors have to be checked in the code, or can be assigned to `_`:
|
必须在代码中检查错误或者赋值给 `_`:
|
||||||
|
|
||||||
```
|
```
|
||||||
n0, _ := Read(Buffer) // ignore error
|
n0, _ := Read(Buffer) // 忽略错误
|
||||||
n, err := Read(buffer)
|
n, err := Read(buffer)
|
||||||
if err != nil {
|
if err != nil {
|
||||||
return err
|
return err
