NativeFromBinary should give error instead of giving empty slice in case of failure in decoding.

Hi there,
Consider below struct: [struct1]

type Personal struct { Addresses []Address json:"addresses" }

type Address struct { StreetName string json:"streetName" validate:"min=6,max=100,noLeadingTrailingSpace" pact:"example=123456,regex=^\d{6}$" }

Consider below avro codec for the same: [struct1]
{ "name": "Personal", "type": "record", "fields": [ { "name": "addresses", "type": { "type": "array", "items": { "type": "record", "name": "Address", "fields": [{ "name": "streetName", "type": "string" } ] } } } ] }

Now consider another struct & it's avro schema: [struct2]

{ "name": "Personal", "type": "record", "fields": [ { "name": "addresses", "type": { "type": "array", "items": { "type": "record", "name": "Address", "fields": [{ "name": "state", "type": "string" } ] } } } ] }

type Personal struct { Addresses []Address json:"addresses" }

type Address struct { State string json:"state" validate:"min=6,max=100,noLeadingTrailingSpace" pact:"example=123456,regex=^\d{6}$" }

Now I'm trying to encode my message using struct2 and decode in struct1 using NativeFromBinary() method i.e.
val, newBuf, err := ac.NativeFromBinary(msg)
Ideal assumption would be to get a decoding error, but instead of getting error I'm getting a Personal(struct1) containing empty Addresses slice into val & newBuf containing other remaining bytes(undecoded) and err is nil.
I think this is shouldn't be the case. Please see!
