Go reflection with interface embedded in struct – how to detect “real” functions?

by

You needn’t reflection to my mind

method_in_table := B.Foo
fmt.Printf("%T \n", method_in_table)

will output you

func(main.B) string

Interface type A initialized at predeclared nil which has no dynamic type

var a A
if a==nil{
    fmt.Printf("It's nil")
}
a.Foo()

will give you same error. So practical check can be just

if b.A != nil { b.Foo()}
