random, encode, decode incoherence

[yovanoc]

From just the main example on the docs, and added random and protobuf I observed strange behaviors with each launch.

code:

import typia, { tags } from "typia";

export const encode = typia.protobuf.createEncode<Customer>();
export const decode = typia.protobuf.createDecode<Customer>();

type Customer = {
    id: number & tags.Type<"int32">;
    email: string & tags.Format<"email">;
    name: string;
    pet: null | Cat | Dog;
    memo: null | Map<string, string>;
    logins: Array<CustomerLogin>;
}

type Cat = {
    type: "cat";
    name: string;
    ribbon: boolean;
}
type Dog = {
    type: "dog";
    name: string;
    hunt: boolean;
}
type CustomerLogin = {
    success: boolean;
    href: string & tags.Format<"url">;
    referrer: string & tags.Format<"url">;
    ip: string & (tags.Format<"ipv4"> | tags.Format<"ipv6">);
    time: string & tags.Format<"date-time">;
}

const customer = typia.random<Customer>();
console.dir(customer, { depth: 10 });
const encoded = encode(customer);
console.log(encoded);
const decoded = decode(encoded);
console.dir(decoded, { depth: 10 });

console.log(typia.is<Customer>(decoded));
console.log(typia.is<Customer>({}));

logs:
1.

true
false

here the logins are correct but memo is null after decode but was created empty with the random

true

here it completely ignore logins..

I don't know what is going on, but maybe someone can explain this to me.

thanks

Good Point.

Fixed the bug that stopping the encoding when union type comes. Upgrade to the v5.3.5 version please.

By the way, Protocol Buffer does not write any data when undefined, null and Array.length := 0 value comes. Therefore, no way to distinguish which empty value being used when Array | undefined | null type comes. It is not a bug, but spec of typia library considering such characteristics of Protocol Buffer spec.

Yes, you are right about protobuf. v5.3.5 works great!
