Variants

ArrivalTimeIsForTransitOnly(String, String)

An arrival time may only be specified in Transit travel mode.

EitherAlternativesOrWaypoints(usize)

Alternatives may not be requested when waypoints are specified.

EitherDepartureTimeOrArrivalTime(String, String)

An departure time may not be specified when an arrival time is specified.

EitherRestrictionsOrWaypoints(usize, String)

Restrictions may not be specified when waypoints are specified.

EitherWaypointsOrTransitMode(usize)

GoogleMapsService(Status, Option<String>)

Google Maps Directions API service generated an error. See the Status enum for more information.

HttpUnsuccessful(u8, String)

The HTTP request was unsuccessful.

InvalidAvoidCode(String)

API client library attempted to parse a string that contained an invalid avoid/restrictions code. See google_maps\src\directions\request\avoid.rs for more information.

InvalidCurrencyCode(String)

API client library attempted to parse a string that contained an invalid currency code. See google_maps\src\directions\response\currency.rs for more information.

InvalidGeocoderStatusCode(String)

API client library attempted to parse a string that contained an invalid geocoder status code. See google_maps\src\directions\response\geocoder_status.rs for more information.

InvalidDrivingManeuverCode(String)

API client library attempted to parse a string that contained an invalid maneuver type code. See google_maps\src\directions\response\maneuver_type.rs for more information.

InvalidStatusCode(String)

API client library attempted to parse a string that contained an invalid status code. See google_maps\src\directions\response\status.rs for more information.

InvalidTransitRoutePreferenceCode(String)

API client library attempted to parse a string that contained an invalid transit routing preference code. See google_maps\src\directions\request\transit_route_preference.rs for more information.

InvalidTravelModeCode(String)

API client library attempted to parse a string that contained an invalid travel mode code. See google_maps\src\directions\travel_mode.rs for more information.

QueryNotBuilt

The query string must be built before the request may be sent to the Google Maps Directions API service.

RequestNotValidated

The request must be validated before a query string may be built.

Reqwest(Error)

The dependency library Reqwest generated an error.

SerdeJson(Error)

The dependency library Serde JSON generated an error.

TooManyWaypoints(usize)

Too many waypoints specified.

TransitModeIsForTransitOnly(String, String)

Transit mode may only be specified in Transit travel mode.

TransitRoutePreferenceIsForTransitOnly(String, String)

Transit routing preference may only be specified in Transit travel mode.

Trait Implementations

impl Debug for Error

fn fmt(&self, f: &mut Formatter) -> Result

Formats the value using the given formatter.

impl Display for Error

fn fmt(&self, f: &mut Formatter) -> Result

This trait converts the error code into a format that may be presented to the user.

impl Error for Error

fn source(&self) -> Option<&(dyn Error + 'static)>

If the cause for the error is in an underlying library (not this library but a library this one depends on), this trait unwraps the original source error. This trait converts a Google Maps Directions API error type into the native error type of the underlying library.

fn backtrace(&self) -> Option<&Backtrace>

🔬 This is a nightly-only experimental API. (backtrace)

Returns a stack backtrace, if available, of where this error occurred.

fn description(&self) -> &str

Deprecated since 1.42.0:

use the Display impl or to_string()

if let Err(e) = "xc".parse::<u32>() { // Print e itself, no need for description(). eprintln!("Error: {}", e); }

fn cause(&self) -> Option<&dyn Error>

Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

impl From<Error> for Error

fn from(error: Error) -> Error

This trait converts from an Reqwest error type (reqwest::Error) into a Google Maps Directions API error type (google_maps::directions::error::Error) by wrapping it inside. This function is required to use the ? operator.

impl From<Error> for Error

fn from(error: Error) -> Error

This trait converts from an Serde JSON (serde_json::error::Error) error type into a Google Maps Directions API error type (google_maps::directions::error::Error) by wrapping it inside. This function is required to use the ? operator.
