FieldLevel.Field().Type() takes a dynamic value when a field is of a pointer type.

• I have looked at the documentation here first?
• I have looked at the examples provided that may showcase my question here?

Package version eg. v9, v10:

v10

Issue, Question or Enhancement:

When a custom tag defined with RegisterValidation() is added to a field of a pointer type, the FieldLevel passed to the registered function behaves very strangely.

For example, if a validated field is of the type *string, FieldLevel.Field().Type() returns *string if the actual value is nil while it returns string if the actual value is not nil.

I expect it always returns *string because the original field is of the type *string (not string).

Maybe the package auto-dereferences validated fields? But the official documentation says nothing about it.

Code sample, to showcase or reproduce:

package main

import (
	"fmt"

	"github.com/go-playground/validator/v10"
)

type S struct {
	Name *string `validate:"my"`
}

func f(s validator.FieldLevel) bool {
	fmt.Println(s.Field().Type())
	return true
}

func main() {
	validate := validator.New()
	err := validate.RegisterValidation("my", f)
	if err != nil {
		panic(err)
	}

	{
		s := S{
			Name: nil,
		}
		_ = validate.Struct(s) //=> *string
	}

	{
		ss := "black"
		s := S{
			Name: &ss,
		}
		_ = validate.Struct(s) //=> string
	}
}
