Go interface with String() method

Question

Is there a Go interface in the standard library with:

String() string

?

(Similar to how Java has toString() on java.lang.Object)

Perhaps I just didn't search enough but I didn't see one. Wanted to use one that already exists rather than than making my own (though I guess it really makes no difference with Go's type system).

You could use the implements tool to answer questions of this form. In this case, you'd find any package that has structs with String() methods, say, time, which has quite a few, and then run implements -types time, and look at the interfaces it says are implemented by the various time types. — Tyler

fmt.Stringer is what you're after.

type Stringer interface {
        String() string
}

The closest thing I've seen to Java's toString is fmt#Stringer.
