Min() validator fails on uint32 field

[mklimuk]

I stumbled upon this when trying to validate a struct with uint32 field. The validation fails with

Integer: cannot convert uint32 to int64.

Here's a complete test case:

package main

import (
	"fmt"
	"testing"

	"github.com/go-ozzo/ozzo-validation"
)

type A struct {
	Integer uint32
}

func (a A) Validate() error {
	return validation.ValidateStruct(&a,
		validation.Field(&a.Integer, validation.Required, validation.Min(1)))
}

func TestValidate(t *testing.T) {
	a := A{2}
	err := a.Validate()
	if err != nil {
		fmt.Printf("validation error received: %s", err.Error())
		t.Fail()
	}
}

After some digging in I suppose the error is due to the fact that Indirect(value interface{}) (interface{}, bool) method does not resolve pointers to uint32 properly. I'll try to issue a PR if I manage to fix the issue.

Ok, my bad. It just requires to set the validator value in the target type. So validation.Min(uint32(1)) fixed it for me. Closing...
