Documentation

Overview

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

Manages user-provided workflows.

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.

Functions

func DefaultAuthScopes

func DefaultAuthScopes() []string

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

Types

type 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.

type 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/apiv1beta"
)

func main() {
	ctx := context.Background()
	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/apiv1beta"

	executionspb "google.golang.org/genproto/googleapis/cloud/workflows/executions/v1beta"
)

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

	req := &executionspb.CancelExecutionRequest{
		// TODO: Fill request struct fields.
	}
	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

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

Connection returns a connection to the API service.

Deprecated.

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/apiv1beta"

	executionspb "google.golang.org/genproto/googleapis/cloud/workflows/executions/v1beta"
)

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

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

Example

package main

import (
	"context"

	executions "cloud.google.com/go/workflows/executions/apiv1beta"

	executionspb "google.golang.org/genproto/googleapis/cloud/workflows/executions/v1beta"
)

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

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

func (*Client) ListExecutions

func (c *Client) ListExecutions(ctx context.Context, req *executionspb.ListExecutionsRequest, opts ...gax.CallOption) *ExecutionIterator

ListExecutions returns a list of executions which belong to the workflow with the given name. The method returns executions of all workflow revisions. Returned executions are ordered by their start time (newest first).

Example

package main

import (
	"context"

	executions "cloud.google.com/go/workflows/executions/apiv1beta"
	"google.golang.org/api/iterator"

	executionspb "google.golang.org/genproto/googleapis/cloud/workflows/executions/v1beta"
)

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

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

type 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) 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.
