|
In-memory data store for the Veterinary Clinic example.
|
|
|
|
This module is NOT thread-safe and is intended for demos and scaffolds only.
|
|
|
|
It provides minimal, process-local data stores for the five veterinary
|
|
clinic entities. Each store exposes standard CRUD operations backed by
|
|
a simple dictionary.
|
|
|
|
This module intentionally avoids:
|
|
- persistence
|
|
- concurrency guarantees
|
|
- transactional semantics
|
|
- validation beyond what Pydantic provides
|
|
|
|
This module is not part of the ``openapi_first`` library API surface.
