How to override a method of an embedded struct in Go?

To override a method of an embedded struct in Go, you can define a method with the same name and signature in the outer struct.

Here is an example:

package main

import "fmt"

// base struct
type Base struct{}

// method to be overridden
func (b Base) Method() {
    fmt.Println("Base method")
}

// struct embedding the Base struct
type Derived struct {
    Base
}

// override the Method of the embedded struct
func (d Derived) Method() {
    fmt.Println("Override method")
}

func main() {
    // create an instance of Derived
    d := Derived{}
    
    // call the overridden method
    d.Method()  // Output: Override method
}

In this example, we have two structs Base and Derived. The Derived struct embeds the Base struct. By defining the Method function in the Derived struct, we are able to override the method of the embedded Base struct. When calling d.Method(), it will call the overridden method and print "Override method".
