Package storagetransfer is an auto-generated package for the Storage Transfer API.
Transfers data from external data sources to a Google Cloud Storage bucket or between Google Cloud Storage buckets.
NOTE : This package is in beta . It is not stable , and may be subject to changes .
Use of Context
The ctx passed to NewClient 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.
For information about setting deadlines, reusing contexts, and more please visit https://pkg.go.dev/cloud.google.com/go .

Client is a client for interacting with Storage Transfer API. Methods, except Close, may be called concurrently. However, fields must not be modified concurrently with method calls.
Storage Transfer Service and its protos. Transfers data between between Google Cloud Storage buckets or from a data source external to Google to a Cloud Storage bucket.
func NewClient
NewClient creates a new storage transfer service client based on gRPC. The returned client must be Closed when it is done being used to clean up its underlying connections.

GetGoogleServiceAccount returns the Google service account that is used by Storage Transfer Service to access buckets in the project where transfers run or in other projects. Each Google service account is associated with one Google Cloud Platform Console project. Users should add this service account to the Google Cloud Storage bucket ACLs to grant access to Storage Transfer Service. This service account is created and owned by Storage Transfer Service and can only be used by Storage Transfer Service.

UpdateTransferJob updates a transfer job. Updating a job’s transfer spec does not affect transfer operations that are running already.
Note: The job’s status field can be modified using this RPC (for example, to set a job’s status to DELETED, DISABLED, or ENABLED).

RunTransferJobOperation
type
RunTransferJobOperation
struct
{
// contains filtered or unexported fields
}
RunTransferJobOperation manages a long-running operation from RunTransferJob.
func (*RunTransferJobOperation) Done
func
(
op
*
RunTransferJobOperation
)
Done
()
bool
Done reports whether the long-running operation has completed.
func (*RunTransferJobOperation) Metadata
func
(
op
*
RunTransferJobOperation
)
Metadata
()
(
*
storagetransferpb
.
TransferOperation
,
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 (*RunTransferJobOperation) Name
func
(
op
*
RunTransferJobOperation
)
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 (*RunTransferJobOperation) Poll
func
(
op
*
RunTransferJobOperation
)
Poll
(
ctx
context
.
Context
,
opts
...
gax
.
CallOption
)
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 (*RunTransferJobOperation) Wait
func
(
op
*
RunTransferJobOperation
)
Wait
(
ctx
context
.
Context
,
opts
...
gax
.
CallOption
)
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.
TransferJobIterator
type

// 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.

TransferJobIterator manages a stream of *storagetransferpb.TransferJob.
func (*TransferJobIterator) Next
func
(
it
*
TransferJobIterator
)
Next
()
(
*
storagetransferpb

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 (*TransferJobIterator) PageInfo
func
(

TransferJobIterator
)
PageInfo

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