Documentation

Overview

Package control is an auto-generated package for the Cloud Storage API.

Lets you store and retrieve potentially-large, immutable data objects. 

NOTE: This package is in beta. It is not stable, and may be subject to changes.

General documentation

For information that is relevant for all client libraries please reference https://pkg.go.dev/cloud.google.com/go#pkg-overview. Some information on this page includes:

Example usage

To get started with this package, create a client. 

ctx := context.Background()
// This snippet has been automatically generated and should be regarded as a code template only.
// It will require modifications to work:
// - It may require correct/in-range values for request initialization.
// - It may require specifying regional endpoints when creating the service client as shown in:
//   https://pkg.go.dev/cloud.google.com/go#hdr-Client_Options
c, err := control.NewStorageControlClient(ctx)
if err != nil {
	// TODO: Handle error.
}
defer c.Close()

The client will use your default application credentials. Clients should be reused instead of created as needed. The methods of Client are safe for concurrent use by multiple goroutines. The returned client must be Closed when it is done being used.

Using the Client

The following is an example of making an API call with the newly created client. 

ctx := context.Background()
// This snippet has been automatically generated and should be regarded as a code template only.
// It will require modifications to work:
// - It may require correct/in-range values for request initialization.
// - It may require specifying regional endpoints when creating the service client as shown in:
//   https://pkg.go.dev/cloud.google.com/go#hdr-Client_Options
c, err := control.NewStorageControlClient(ctx)
if err != nil {
	// TODO: Handle error.
}
defer c.Close()

req := &controlpb.CreateFolderRequest{
	// TODO: Fill request struct fields.
	// See https://pkg.go.dev/cloud.google.com/go/storage/control/apiv2/controlpb#CreateFolderRequest.
}
resp, err := c.CreateFolder(ctx, req)
if err != nil {
	// TODO: Handle error.
}
// TODO: Use resp.
_ = resp

Use of Context

The ctx passed to NewStorageControlClient is used for authentication requests and for creating the underlying connection, but is not used for subsequent calls. Individual methods on the client use the ctx given to them.

To close the open connection, use the Close() method.

Functions

func DefaultAuthScopes 

func DefaultAuthScopes() []string

DefaultAuthScopes reports the default set of authentication scopes to use with this package.

Types

type FolderIterator 

type FolderIterator struct {

	// Response is the raw response for the current page.
	// It must be cast to the RPC response type.
	// Calling Next() or InternalFetch() updates this value.
	Response interface{}

	// InternalFetch is for use by the Google Cloud Libraries only.
	// It is not part of the stable interface of this package.
	//
	// InternalFetch returns results from a single call to the underlying RPC.
	// The number of results is no greater than pageSize.
	// If there are no more results, nextPageToken is empty and err is nil.
	InternalFetch func(pageSize int, pageToken string) (results []*controlpb.Folder, nextPageToken string, err error)
	// contains filtered or unexported fields
}

FolderIterator manages a stream of *controlpb.Folder.

func (*FolderIterator) Next 

func (it *FolderIterator) Next() (*controlpb.Folder, error)

Next returns the next result. Its second return value is iterator.Done if there are no more results. Once Next returns Done, all subsequent calls will return Done.

func (*FolderIterator) PageInfo 

func (it *FolderIterator) PageInfo() *iterator.PageInfo

PageInfo supports pagination. See the google.golang.org/api/iterator package for details.

type RenameFolderOperation 

type RenameFolderOperation struct {
	// contains filtered or unexported fields
}

RenameFolderOperation manages a long-running operation from RenameFolder.

func (*RenameFolderOperation) Done 

func (op *RenameFolderOperation) Done() bool

Done reports whether the long-running operation has completed.

func (*RenameFolderOperation) Metadata 

func (op *RenameFolderOperation) Metadata() (*controlpb.RenameFolderMetadata, error)

Metadata returns metadata associated with the long-running operation. Metadata itself does not contact the server, but Poll does. To get the latest metadata, call this method after a successful call to Poll. If the metadata is not available, the returned metadata and error are both nil.

func (*RenameFolderOperation) Name 

func (op *RenameFolderOperation) Name() string

Name returns the name of the long-running operation. The name is assigned by the server and is unique within the service from which the operation is created.

func (*RenameFolderOperation) Poll 

func (op *RenameFolderOperation) Poll(ctx context.Context, opts ...gax.CallOption) (*controlpb.Folder, error)

Poll fetches the latest state of the long-running operation.

Poll also fetches the latest metadata, which can be retrieved by Metadata.

If Poll fails, the error is returned and op is unmodified. If Poll succeeds and the operation has completed with failure, the error is returned and op.Done will return true. If Poll succeeds and the operation has completed successfully, op.Done will return true, and the response of the operation is returned. If Poll succeeds and the operation has not completed, the returned response and error are both nil.

func (*RenameFolderOperation) Wait 

func (op *RenameFolderOperation) Wait(ctx context.Context, opts ...gax.CallOption) (*controlpb.Folder, error)

Wait blocks until the long-running operation is completed, returning the response and any errors encountered.

See documentation of Poll for error-handling information.

type StorageControlCallOptions 

type StorageControlCallOptions struct {
	CreateFolder     []gax.CallOption
	DeleteFolder     []gax.CallOption
	GetFolder        []gax.CallOption
	ListFolders      []gax.CallOption
	RenameFolder     []gax.CallOption
	GetStorageLayout []gax.CallOption
}

StorageControlCallOptions contains the retry settings for each method of StorageControlClient.

type StorageControlClient 

type StorageControlClient struct {

	// The call options for this service.
	CallOptions *StorageControlCallOptions

	// LROClient is used internally to handle long-running operations.
	// It is exposed so that its CallOptions can be modified if required.
	// Users should not Close this client.
	LROClient *lroauto.OperationsClient
	// contains filtered or unexported fields
}

StorageControlClient 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.

StorageControl service includes selected control plane operations.

func NewStorageControlClient 

func NewStorageControlClient(ctx context.Context, opts ...option.ClientOption) (*StorageControlClient, error)

NewStorageControlClient creates a new storage control client based on gRPC. The returned client must be Closed when it is done being used to clean up its underlying connections.

StorageControl service includes selected control plane operations.

Example 
package main

import (
	"context"

	control "cloud.google.com/go/storage/control/apiv2"
)

func main() {
	ctx := context.Background()
	// This snippet has been automatically generated and should be regarded as a code template only.
	// It will require modifications to work:
	// - It may require correct/in-range values for request initialization.
	// - It may require specifying regional endpoints when creating the service client as shown in:
	//   https://pkg.go.dev/cloud.google.com/go#hdr-Client_Options
	c, err := control.NewStorageControlClient(ctx)
	if err != nil {
		// TODO: Handle error.
	}
	defer c.Close()

	// TODO: Use client.
	_ = c
}

Output:

func (*StorageControlClient) Close 

func (c *StorageControlClient) Close() error

Close closes the connection to the API service. The user should invoke this when the client is no longer required.

func (*StorageControlClient) Connection deprecated 

func (c *StorageControlClient) Connection() *grpc.ClientConn

Connection returns a connection to the API service.

Deprecated: Connections are now pooled so this method does not always return the same resource.

func (*StorageControlClient) CreateFolder 

func (c *StorageControlClient) CreateFolder(ctx context.Context, req *controlpb.CreateFolderRequest, opts ...gax.CallOption) (*controlpb.Folder, error)

CreateFolder creates a new folder.

Example 
package main

import (
	"context"

	control "cloud.google.com/go/storage/control/apiv2"
	controlpb "cloud.google.com/go/storage/control/apiv2/controlpb"
)

func main() {
	ctx := context.Background()
	// This snippet has been automatically generated and should be regarded as a code template only.
	// It will require modifications to work:
	// - It may require correct/in-range values for request initialization.
	// - It may require specifying regional endpoints when creating the service client as shown in:
	//   https://pkg.go.dev/cloud.google.com/go#hdr-Client_Options
	c, err := control.NewStorageControlClient(ctx)
	if err != nil {
		// TODO: Handle error.

		// TODO: Fill request struct fields.
		// See https://pkg.go.dev/cloud.google.com/go/storage/control/apiv2/controlpb#CreateFolderRequest.
	}
	resp, err := c.CreateFolder(ctx, req)
	if err != nil {

	}
	// TODO: Use resp.
	_ = resp
}
