用String（）方法转到接口

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).

Answer 1

fmt.Stringer is what you're after.

type Stringer interface {
        String() string
}
