Storage Insights API v1 - Package cloud.google.com/go/storageinsights/apiv1 (v0.2.1)

Package storageinsights is an auto-generated package for the Storage Insights API.

Provides insights capability on Google Cloud Storage

General documentation

For information about setting deadlines, reusing contexts, and more please visit https://pkg.go.dev/cloud.google.com/go.

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

req := &storageinsightspb.ListReportConfigsRequest{
    // TODO: Fill request struct fields.
    // See https://pkg.go.dev/cloud.google.com/go/storageinsights/apiv1/storageinsightspb#ListReportConfigsRequest.
}
it := c.ListReportConfigs(ctx, req)
for {
    resp, err := it.Next()
    if err == iterator.Done {
        break
    }
    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 {
	ListReportConfigs  []gax.CallOption
	GetReportConfig    []gax.CallOption
	CreateReportConfig []gax.CallOption
	UpdateReportConfig []gax.CallOption
	DeleteReportConfig []gax.CallOption
	ListReportDetails  []gax.CallOption
	GetReportDetail    []gax.CallOption
	GetLocation        []gax.CallOption
	ListLocations      []gax.CallOption
	CancelOperation    []gax.CallOption
	DeleteOperation    []gax.CallOption
	GetOperation       []gax.CallOption
	ListOperations     []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 Storage Insights API. Methods, except Close, may be called concurrently. However, fields must not be modified concurrently with method calls.

Service describing handlers for resources

func NewClient

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

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