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 .

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
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.

// Calling Next() or InternalFetch() updates this value.
Response

// 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.

ExecutionIterator manages a stream of *executionspb.Execution.
func (*ExecutionIterator) Next
func
