I have written a simple code in Go but I am getting a weird error. I have attached a screenshot of code and error.

error: func main is unused

Code:

package structs

import "fmt"

func main() {
    fmt.Println("Hello Structs")
}

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.
