How to generate a uuid in form of [u8; 16] in rust dfinity ICP?

Question

I tried this way, but the canister seems to have difficulties serialise the [u8; 16], I also tried to use the Uuid package and the canister failed even when I just use Uuid::preload::*;

#[update]
#[candid_method(update)]
pub async fn test_create_id() -> String {
    let id: ([u8; 16], ) = ic_cdk::api::call::call(
        ic_cdk::export::Principal::management_canister(),
        "raw_rand",
        (),
    ).await.unwrap(); //<---- it is Panicking here?
    return format!("{:#?}", id)
}

[Canister rrkah-fqaaa-aaaaa-aaaaq-cai] Panicked at 'called `Result::unwrap()` on an `Err` value: (CanisterError, "failed to decode canister response as (): Trailing value after finishing deserialization")', canisters/backend/src/files/update.rs:73:34
[Canister rrkah-fqaaa-aaaaa-aaaaq-cai] Panicked at 'called `Result::unwrap()` on an `Err` value: (NoError, "cleanup")', canisters/backend/src/files/update.rs:73:34

Maybe there are other ways to generate Uuids?
