Example of using struct enbeding to implement an interface: https://play.golang.org/p/9RAY8RI7_N7

struct_embedding.go

package main

import (
	"fmt"
)

type A struct {
	B string
}

func (a *A) Value() string {
	return a.B
}

type C struct {
	*A
}

// C does not implement the interface, but A does and C contains it
//func (c *C) Value() string {
//	return c.A.Value()
//}

type Z interface {
	Value() string
}

var _ Z = (*C)(nil) // The compiler checks that C implements Z (via A) here

func main() {
	a := &A{"hello"}
	c := &C{a}

	fmt.Println(c.Value())
}
