// Package travelimpactmodel provides access to the Travel Impact Model API.
//
// For product documentation, see: https://developers.google.com/travel/impact-model
//
// # Library status
//
// These client libraries are officially supported by Google. However, this
// library is considered complete and is in maintenance mode. This means
// that we will address critical bugs and security issues but will not add
// any new features.
//
// When possible, we recommend using our newer
// [Cloud Client Libraries for Go](https://pkg.go.dev/cloud.google.com/go)
// that are still actively being worked and iterated on.
//
// # Creating a client
//
// Usage example:
//
//	import "google.golang.org/api/travelimpactmodel/v1"
//	...
//	ctx := context.Background()
//	travelimpactmodelService, err := travelimpactmodel.NewService(ctx)
//
// In this example, Google Application Default Credentials are used for
// authentication. For information on how to create and obtain Application
// Default Credentials, see https://developers.google.com/identity/protocols/application-default-credentials.
//
// # Other authentication options
//
// To use an API key for authentication (note: some APIs do not support API
// keys), use [google.golang.org/api/option.WithAPIKey]:
//
//	travelimpactmodelService, err := travelimpactmodel.NewService(ctx, option.WithAPIKey("AIza..."))
//
// To use an OAuth token (e.g., a user token obtained via a three-legged OAuth
// flow, use [google.golang.org/api/option.WithTokenSource]:
//
//	config := &oauth2.Config{...}
//	// ...
//	token, err := config.Exchange(ctx, ...)
//	travelimpactmodelService, err := travelimpactmodel.NewService(ctx, option.WithTokenSource(config.TokenSource(ctx, token)))
//
// See [google.golang.org/api/option.ClientOption] for details on options.

// TIM-based emissions given origin, destination, carrier, flightNumber,
// departureDate, and cabinClass. 2. Typical flight emissions given origin,
// destination, year in departureDate, and cabinClass. 3. Distance-based
// emissions calculated using distanceKm, year in departureDate, and
// cabinClass. If there is a future flight requested in this calendar year, we
// do not support Tier 1 emissions and will fallback to Tier 2 or 3 emissions.
// If the requested future flight is in not in this calendar year, we will

// will return a Scope3FlightEmissions object with empty emission fields. The
// request will still be considered successful. Generally, missing emissions
// estimates occur when the flight is unknown to the server (e.g. no specific
// flight exists, or typical flight emissions are not available for the
// requested pair). The request will fail with an `INVALID_ARGUMENT` error if:
// * The request contains more than 1,000 flight legs. * The input flight leg

// without a valid distance for TIM_EMISSIONS or TYPICAL_FLIGHT_EMISSIONS type
// matching, or missing distance for a DISTANCE_BASED_EMISSIONS type matching
// (if you want to fallback to distance-based emissions or want a
// distance-based emissions estimate, you need to specify a distance). * The
// flight date is before 2019 (Scope 3 data is only available for 2019 and
// after). * The flight distance is 0 or lower. * Missing cabin class. Because
// the request is processed with fallback logic, it is possible that
// misconfigured requests return valid emissions estimates using fallback
// methods. For example, if a request has the wrong flight number but specifies
// the origin and destination, the request will still succeed, but the returned
// emissions will be based solely on the typical flight emissions. Similarly,
// if a request is missing the origin for a typical flight emissions request,
