Base class for the server implementation of the service Storage.
## API Overview and Naming Syntax
The Cloud Storage gRPC API allows applications to read and write data through
the abstractions of buckets and objects. For a description of these
abstractions please see https://cloud.google.com/storage/docs.
Resources are named as follows:
- Projects are referred to as they are defined by the Resource Manager API,
using strings like `projects/123456` or `projects/my-string-id`.
- Buckets are named using string names of the form:
`projects/{project}/buckets/{bucket}`
For globally unique buckets, `_` may be substituted for the project.
- Objects are uniquely identified by their name along with the name of the
bucket they belong to, as separate strings in this API. For example:
ReadObjectRequest {
bucket: 'projects/_/buckets/my-bucket'
object: 'my-object'
}
Note that object names can contain `/` characters, which are treated as
any other character (no special directory semantics).
