1.0 update usage question

從 issue 中的 GuestAddressTest 範例開始，檢視 ValidatorFactory 的設定以及它所演示的 violation 欄位。判定並記錄 1.0 支援的、用於檢查 constraint 與欄位詳細資訊的用法，包括 nullable 屬性和 descriptor 路徑；範例應清楚地展示預期的 assertions。

I'm updating to the 1.0 version of protovalidate-java, and there's a breaking change in how I consume the violations that I'm confused by.

Given this sample message:

message GuesAAddress {
  optional string zip_code = 1 [
    (buf.validate.field).required = true,
    (buf.validate.field).string.len = 5
  ];
}

I guessed at the changes I needed to make to unit test this.

 package common.guest.v1

+            ruleValue?.descriptor?.fullName shouldBe "buf.validate.StringRules.len"
         }
     }
 }

Is what I did the expected usage change, or is there a cleaner way to inspect the fields? Them being nullable felt odd, and the path to get to those fields was not obvious to me.

Appreciate it - thanks.
