从不同的包golang实现接口

我在尝试实现接口（在golang的其他程序包中定义）时遇到了一些问题。我对下面的问题做了些微的阐述

接口：

package interfaces

type Interface interface {
    do(param int) int
}

实现方式：

package implementations

type Implementation struct{}

func (implementation *Implementation) do(param int) int {
    return param
}

Main.go：

package main

import (
    "test/implementing-interface-in-different-package/implementations"
    "test/implementing-interface-in-different-package/interfaces"
)

func main() {
    var interfaceImpl interfaces.Interface
    interfaceImpl = &implementations.Implementation{}
}

错误信息：

test/implementing-interface-in-different-package
./main.go:10:16: cannot use implementations.Implementation literal (type 
implementations.Implementation) as type interfaces.Interface in assignment:
    implementations.Implementation does not implement interfaces.Interface (missing interfaces.do method)
            have implementations.do(int) int
            want interfaces.do(int) int

是否可以从其他包中实现接口？

谢谢！
