| // Client is a client for interacting with Cloud Storage API. |
| // Methods, except Close, may be called concurrently. However, fields must not be modified concurrently with method calls. |
| // |
| // API Overview and Naming SyntaxThe 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 (at 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). |

| // abstractions please see https://cloud.google.com/storage/docs (at 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). |
