Converting a custom type to string in Go

Question

In this bizarre example, someone has created a new type which is really just a string:

type CustomType string  const (         Foobar CustomType = "somestring" )  func SomeFunction() string {         return Foobar } 

However, this code fails to compile:

cannot use Foobar (type CustomType) as type string in return argument

How would you fix SomeFunction so that it is able to return the string value of Foobar ("somestring") ?

Answer 1

Convert the value to a string:

func SomeFunction() string {         return string(Foobar) }
