How to Access Fields of Embedded Structures in Go Validation Methods?

Accessing Struct Fields in Embedded Structures

In Go, defining methods on structs for validation purposes is common. However, accessing fields of embedded structures within those methods can be challenging.

Let's examine the provided code:

<code class="go">package main

import "log"

type ReqAbstract struct{}

func (r *ReqAbstract) Validate() error {
    log.Printf("%+v", r)
    return nil
}
func (r *ReqAbstract) Validate2(req interface{}) error {
    log.Printf("%+v", req)
    return nil
}

type NewPostReq struct {
    ReqAbstract</code>
