getting an error in go: func main is unused
问题
我在Go语言中编写了一段简单的代码，但是出现了一个奇怪的错误。我已经附上了代码和错误的截图。
错误信息：func main is unused
代码：
package structs
import "fmt"
func main() {
fmt.Println("Hello Structs")
}

将package structs更改为package main。
https://golang.org/ref/spec#Program_execution
> 通过将一个名为main package的未导入包与其直接或间接导入的所有包链接，可以创建一个完整的程序。主包必须具有包名main并声明一个不带参数且不返回值的main函数。
请注意，func main is unused本身并不是一个错误，它只是来自go-staticcheck linter的未使用代码的报告。未使用的函数是允许的，但是如果我没有弄错的话，它们将被省略在输出的二进制文件中。
英文:
Change package structs to package main.
https://golang.org/ref/spec#Program_execution
> A complete program is created by linking a single, unimported package
> called the main package with all the packages it imports,
> transitively. The main package must have package name main and declare
> a function main that takes no arguments and returns no value.
Note that func main is unused by itself is not an error, it is just a report of an instance of unused code from the go-staticcheck linter. Unused functions are allowed by the Go compiler, but they will be, if I'm not mistaken, omitted from the output binary.
