Workflow Executions API v1 - Package cloud.google.com/go/workflows/executions/apiv1 (v1.13.2)

Package executions is an auto-generated package for the Workflow Executions API.

Execute workflows created with Workflows API.

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 := executions.NewClient(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 := executions.NewClient(ctx)
if err != nil {
    // TODO: Handle error.
}
defer c.Close()

req := &executionspb.CancelExecutionRequest{
    // TODO: Fill request struct fields.
    // See https://pkg.go.dev/cloud.google.com/go/workflows/executions/apiv1/executionspb#CancelExecutionRequest.
}
resp, err := c.CancelExecution(ctx, req)
if err != nil {
    // TODO: Handle error.
}
// TODO: Use resp.
_ = resp

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.

Functions

func DefaultAuthScopes

func DefaultAuthScopes() []string

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

CallOptions

type CallOptions struct {
	ListExecutions  []gax.CallOption
	CreateExecution []gax.CallOption
	GetExecution    []gax.CallOption
	CancelExecution []gax.CallOption
}

CallOptions contains the retry settings for each method of Client.

Client

type Client struct {

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

Client is a client for interacting with Workflow Executions API. Methods, except Close, may be called concurrently. However, fields must not be modified concurrently with method calls.

Executions is used to start and manage running instances of Workflows called executions.

func NewClient

func NewClient(ctx context.Context, opts ...option.ClientOption) (*Client, error)

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

Executions is used to start and manage running instances of Workflows called executions.

Example

package main

import (
	"context"

	executions "cloud.google.com/go/workflows/executions/apiv1"
)

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 := executions.NewClient(ctx)
	if err != nil {
		// TODO: Handle error.
	}
	defer c.Close()

	// TODO: Use client.
	_ = c
}

func (*Client) CancelExecution

func (c *Client) CancelExecution(ctx context.Context, req *executionspb.CancelExecutionRequest, opts ...gax.CallOption) (*executionspb.Execution, error)

CancelExecution cancels an execution of the given name.

Example

package main

import (
	"context"

	executions "cloud.google.com/go/workflows/executions/apiv1"
	executionspb "cloud.google.com/go/workflows/executions/apiv1/executionspb"
)

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 := executions.NewClient(ctx)
	if err != nil {
		// TODO: Handle error.
	}
	defer c.Close()

	req := &executionspb.CancelExecutionRequest{
		// TODO: Fill request struct fields.
		// See https://pkg.go.dev/cloud.google.com/go/workflows/executions/apiv1/executionspb#CancelExecutionRequest.
	}
	resp, err := c.CancelExecution(ctx, req)
	if err != nil {
		// TODO: Handle error.
	}
	// TODO: Use resp.
	_ = resp
}

func (*Client) Close

func (c *Client) Close() error

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

func (*Client) Connection (deprecated)

func (c *Client) 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 (*Client) CreateExecution

func (c *Client) CreateExecution(ctx context.Context, req *executionspb.CreateExecutionRequest, opts ...gax.CallOption) (*executionspb.Execution, error)

CreateExecution creates a new execution using the latest revision of the given workflow.

Example

package main

import (
	"context"

	executions "cloud.google.com/go/workflows/executions/apiv1"
	executionspb "cloud.google.com/go/workflows/executions/apiv1/executionspb"
)

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:

	_ = resp
}

func (*Client) GetExecution

func (c *Client) GetExecution(ctx context.Context, req *executionspb.GetExecutionRequest, opts ...gax.CallOption) (*executionspb.Execution, error)

GetExecution returns an execution of the given name.

		resp, err := it.Next()
		if err == iterator.Done {
			break
		}
		if err != nil {
			// TODO: Handle error.
		}
		// TODO: Use resp.
		_ = resp

		// If you need to access the underlying RPC response,
		// you can do so by casting the `Response` as below.
		// Otherwise, remove this line. Only populated after
		// first call to Next(). Not safe for concurrent access.
		_ = it.Response.(*executionspb.ListExecutionsResponse)
	}
}

ExecutionIterator

type ExecutionIterator 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 []*executionspb.Execution, nextPageToken string, err error)
	// contains filtered or unexported fields
}

ExecutionIterator manages a stream of *executionspb.Execution.

func (*ExecutionIterator) All

func (it *ExecutionIterator) All() iter.Seq2[*executionspb.Execution, error]

All returns an iterator. If an error is returned by the iterator, the iterator will stop after that iteration.

func (*ExecutionIterator) Next

func (it *ExecutionIterator) Next() (*executionspb.Execution, 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 (*ExecutionIterator) PageInfo

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

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