// A Case is an object that contains the details of a support case. It
// contains fields for the time it was created, its priority, its
// classification, and more. Cases can also have comments and attachments that
// get added over time.
//
// A case is parented by a Google Cloud organization or project.
//
// Organizations are identified by a number, so the name of a case parented by
// an organization would look like this:
//
// ```
// organizations/123/cases/456
// ```
//
// Projects have two unique identifiers, an ID and a number, and they look like
// this:
//
// ```
// projects/abc/cases/456
// ```
//
// ```
// projects/123/cases/456
// ```
//
// You can use either of them when calling the API. To learn more
// about project identifiers, see [AIP-2510](https://google.aip.dev/cloud/2510).
