timeweb-rs 0.2.0

// Regression test for the `response_id: null` deserialization bug.
//
// Timeweb's live API returns `response_id: null` on some responses (e.g.
// `GET /api/v1/account/finances`), even though the spec types it as a
// required `uuid`. The generated models must tolerate the null — they
// type `response_id` as `Option<uuid::Uuid>` (see
// `openapi/normalize_spec.py::nullable_response_id`). This test pins that
// behaviour so a future regeneration can't silently reintroduce a
// non-optional `response_id`.
