// Package vision is an auto-generated package for the
// Cloud Vision API.
//
// Integrates Google Vision features, including image labeling, face, logo,
// and landmark detection, optical character recognition (OCR), and detection
// of explicit content, into applications.
//
// # 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:
//
//   - [Authentication and Authorization]
//   - [Timeouts and Cancellation]
//   - [Testing against Client Libraries]
//   - [Debugging Client Libraries]
//   - [Inspecting errors]
//
// # 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 := vision.NewProductSearchClient(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 := vision.NewProductSearchClient(ctx)
//	if err != nil {
//		// TODO: Handle error.
//	}
//	defer c.Close()
//
//	req := &visionpb.AddProductToProductSetRequest{
//		// TODO: Fill request struct fields.
//		// See https://pkg.go.dev/cloud.google.com/go/vision/v2/apiv1/visionpb#AddProductToProductSetRequest.
//	}
//	err = c.AddProductToProductSet(ctx, req)
//	if err != nil {
//		// TODO: Handle error.
//	}
//
// # Use of Context
//
// The ctx passed to NewProductSearchClient 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.
