// Package data is an auto-generated package for the
// Google Analytics Data API.
//
// Accesses report data in Google Analytics.
//
//   NOTE: This package is in alpha. It is not stable, and is likely to change.
//
// Example usage
//
// To get started with this package, create a client.
//  ctx := context.Background()
//  c, err := data.NewAlphaAnalyticsDataClient(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()
//  c, err := data.NewAlphaAnalyticsDataClient(ctx)
//  if err != nil {
//  	// TODO: Handle error.
//  }
//  defer c.Close()
//
//  req := &datapb.RunReportRequest{
//  	// TODO: Fill request struct fields.
//  	// See https://pkg.go.dev/google.golang.org/genproto/googleapis/analytics/data/v1alpha#RunReportRequest.
//  }
//  resp, err := c.RunReport(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.
//
// For information about setting deadlines, reusing contexts, and more
// please visit https://pkg.go.dev/cloud.google.com/go.
