Bool as options in Golang
This only works with booleans :D
import this in your project:
import "github.com/mimoo/Bool"then you can use the Bool.Option type. It contains either a bool or an error:
func thing(arg bool) Bool.Option {
if arg {
return Bool.Ok(true)
}
return Bool.Err(fmt.Errorf("nope"))
}and you are forced to handle it before you can use the value:
switch val := Bool.Match(thing(true)).(type) {
case bool:
fmt.Println("a bool!", val)
case error:
fmt.Println("an err!", val)
}
