Package longrunning is an experimental, auto-generated package for the Google Long Running Operations API.

Use the client at cloud.google.com/go/longrunning in preference to this.

func DefaultAuthScopes Uses

func DefaultAuthScopes() []string

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

type OperationIterator Uses

type OperationIterator struct {

    // 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 []*longrunningpb.Operation, nextPageToken string, err error)
    // contains filtered or unexported fields
}

OperationIterator manages a stream of *longrunningpb.Operation.

func (*OperationIterator) Next Uses

func (it *OperationIterator) Next() (*longrunningpb.Operation, 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 (*OperationIterator) PageInfo Uses

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

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

type OperationsCallOptions Uses

type OperationsCallOptions struct {
    GetOperation    []gax.CallOption
    ListOperations  []gax.CallOption
    CancelOperation []gax.CallOption
    DeleteOperation []gax.CallOption
}

OperationsCallOptions contains the retry settings for each method of OperationsClient.

type OperationsClient Uses

type OperationsClient struct {

    // The call options for this service.
    CallOptions *OperationsCallOptions
    // contains filtered or unexported fields
}

OperationsClient is a client for interacting with Google Long Running Operations API.

func InternalFromConn Uses

func InternalFromConn(conn *grpc.ClientConn) *OperationsClient

InternalFromConn is for use by the google Cloud Libraries only.

InternalFromConn creates OperationsClient from available connection.

func NewOperationsClient Uses

func NewOperationsClient(ctx context.Context, opts ...option.ClientOption) (*OperationsClient, error)

NewOperationsClient creates a new operations client.

Manages long-running operations with an API service.

When an API method normally takes long time to complete, it can be designed to return [Operation][google.longrunning.Operation] to the client, and the client can use this interface to receive the real response asynchronously by polling the operation resource, or pass the operation resource to another API (such as Google Cloud Pub/Sub API) to receive the response. Any API service that returns long-running operations should implement the Operations interface so developers can have a consistent client experience.

Code:

ctx := context.Background()
c, err := longrunning.NewOperationsClient(ctx)
if err != nil {
    // TODO: Handle error.
}
// TODO: Use client.
_ = c

func (*OperationsClient) CancelOperation Uses

func (c *OperationsClient) CancelOperation(ctx context.Context, req *longrunningpb.CancelOperationRequest, opts ...gax.CallOption) error

CancelOperation starts asynchronous cancellation on a long-running operation. The server makes a best effort to cancel the operation, but success is not guaranteed. If the server doesn't support this method, it returns google.rpc.Code.UNIMPLEMENTED. Clients can use [Operations.GetOperation][google.longrunning.Operations.GetOperation] or other methods to check whether the cancellation succeeded or whether the operation completed despite cancellation. On successful cancellation, the operation is not deleted; instead, it becomes an operation with an [Operation.error][google.longrunning.Operation.error] value with a [google.rpc.Status.code][google.rpc.Status.code] of 1, corresponding to Code.CANCELLED.

Code:

ctx := context.Background()
c, err := longrunning.NewOperationsClient(ctx)
if err != nil {
    // TODO: Handle error.
}

req := &longrunningpb.CancelOperationRequest{
// TODO: Fill request struct fields.
}
err = c.CancelOperation(ctx, req)
if err != nil {
    // TODO: Handle error.
}

func (*OperationsClient) Close Uses

func (c *OperationsClient) Close() error

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

func (*OperationsClient) Connection Uses

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

Connection returns the client's connection to the API service.

func (*OperationsClient) DeleteOperation Uses

func (c *OperationsClient) DeleteOperation(ctx context.Context, req *longrunningpb.DeleteOperationRequest, opts ...gax.CallOption) error

DeleteOperation deletes a long-running operation. This method indicates that the client is no longer interested in the operation result. It does not cancel the operation. If the server doesn't support this method, it returns google.rpc.Code.UNIMPLEMENTED.

Code:

ctx := context.Background()
c, err := longrunning.NewOperationsClient(ctx)
if err != nil {
    // TODO: Handle error.
}

req := &longrunningpb.DeleteOperationRequest{
// TODO: Fill request struct fields.
}
err = c.DeleteOperation(ctx, req)
if err != nil {
    // TODO: Handle error.
}

func (*OperationsClient) GetOperation Uses

func (c *OperationsClient) GetOperation(ctx context.Context, req *longrunningpb.GetOperationRequest, opts ...gax.CallOption) (*longrunningpb.Operation, error)

GetOperation gets the latest state of a long-running operation. Clients can use this method to poll the operation result at intervals as recommended by the API service.

Code:

ctx := context.Background()
c, err := longrunning.NewOperationsClient(ctx)
if err != nil {
    // TODO: Handle error.
}

req := &longrunningpb.GetOperationRequest{
// TODO: Fill request struct fields.
}
resp, err := c.GetOperation(ctx, req)
if err != nil {
    // TODO: Handle error.
}
// TODO: Use resp.
_ = resp

func (*OperationsClient) ListOperations Uses

func (c *OperationsClient) ListOperations(ctx context.Context, req *longrunningpb.ListOperationsRequest, opts ...gax.CallOption) *OperationIterator

ListOperations lists operations that match the specified filter in the request. If the server doesn't support this method, it returns UNIMPLEMENTED.

NOTE: the name binding below allows API services to override the binding to use different resource name schemes, such as users/*/operations.

Code:

ctx := context.Background()
c, err := longrunning.NewOperationsClient(ctx)
if err != nil {
    // TODO: Handle error.
}

req := &longrunningpb.ListOperationsRequest{
// TODO: Fill request struct fields.
}
it := c.ListOperations(ctx, req)
for {
    resp, err := it.Next()
    if err == iterator.Done {
        break
    }
    if err != nil {
        // TODO: Handle error.
    }
    // TODO: Use resp.
    _ = resp
}

func (*OperationsClient) SetGoogleClientInfo Uses

func (c *OperationsClient) SetGoogleClientInfo(keyval ...string)

SetGoogleClientInfo sets the name and version of the application in the `x-goog-api-client` header passed on each request. Intended for use by Google-written clients.
