[−][src]Crate google_maps
google_maps
An unofficial Google Maps Platform client for the Rust programming language. This client currently implements the Directions API, Distance Matrix API, Elevation API, Geocoding API, and Time Zone API.
Welcome
This crate is expected to work well and have the more important Google Maps features implemented. It should work well because Reqwest and Serde do most of the heavy lifting! While it's an early release, this crate should work fine as is for most people.
I created this library because I needed several Google Maps Platform features for a project that I'm working on. So, I've decided to spin my library off into a public crate. This is a very small token of gratitude and an attempt to give back to the Rust community. I hope it saves someone out there some work.
I would like for you to be successful with your project! If this crate is not working for you, doesn't work how you think it should, you have requests, or suggestions - please contact me. I'm not always fast at responding but I will respond. Thanks!
Example Directions API Request
use google_maps::*; let directions = DirectionsRequest::new( YOUR_GOOGLE_API_KEY_HERE, // Origin: Canadian Museum of Nature Location::Address(String::from("240 McLeod St, Ottawa, ON K2P 2R1")), // Destination: Canada Science and Technology Museum Location::LatLng { lat: 45.403509, lng: -75.618904 }, ) .with_travel_mode(TravelMode::Transit) .with_arrival_time(PrimitiveDateTime::new( Date::try_from_ymd(2020, 1, 20).unwrap(), Time::try_from_hms(13, 00, 0).unwrap() )) .execute().unwrap(); println!("{:#?}", directions);
Example Distance Matrix API Request
use google_maps::*; // Example request: let distance_matrix = DistanceMatrixRequest::new( YOUR_GOOGLE_API_KEY_HERE, // Origins vec![ // Microsoft Waypoint::Address(String::from("One Microsoft Way, Redmond, WA 98052, United States")), // Apple Waypoint::Address(String::from("Infinite Loop, Cupertino, CA 95014, United States")), ], // Destinations vec![ // Google Waypoint::PlaceId(String::from("ChIJj61dQgK6j4AR4GeTYWZsKWw")), // Mozilla Waypoint::LatLng { lat: 37.387316, lng: -122.060008 }, ], ) .execute().unwrap(); // Dump entire response: println!("{:#?}", distance_matrix);
Example Elevation API Positional Request
use google_maps::*; // Example request: let elevation = ElevationRequest::new(YOUR_GOOGLE_API_KEY_HERE) .positional_request(ElevationLocations::LatLngs(vec![ // Denver, Colorado, the "Mile High City" LatLng { lat: 39.7391536, lng: -104.9847034 }, ])) .execute().unwrap(); // Dump entire response: println!("{:#?}", elevation); // Parsing example: println!("Elevation: {} meters", elevation.results.unwrap()[0].elevation);
Example Geocoding API Request
use google_maps::*; // Example request: let location = GeocodingRequest::new(YOUR_GOOGLE_API_KEY_HERE) .with_address("10 Downing Street London") .execute().unwrap(); // Dump entire response: println!("{:#?}", location); // Parsing example: for result in &location.results { println!( "Latitude: {:.7}, Longitude: {:.7}", result.geometry.location.lat, result.geometry.location.lng ); }
Example Reverse Geocoding API Request
use google_maps::*; // Example request: let location = GeocodingReverseRequest::new( YOUR_GOOGLE_API_KEY_HERE, // 10 Downing St, Westminster, London LatLng { lat: 51.5033635, lng: -0.1276248 } ) .with_result_type(PlaceType::StreetAddress) .execute().unwrap(); // Dump entire response: println!("{:#?}", location); // Parsing example: for result in &location.results { for address_component in &result.address_components { print!("{} ", address_component.short_name); } println!(""); // New line. }
Example Time Zone API Request
use google_maps::*; // Example request: let time_zone = TimeZoneRequest::new( YOUR_GOOGLE_API_KEY_HERE, // St. Vitus Cathedral in Prague, Czechia LatLng { lat: 50.090903, lng: 14.400512 }, PrimitiveDateTime::new( // Tuesday February 15, 2022 Date::try_from_ymd(2022, 2, 15).unwrap(), // 6:00:00 pm Time::try_from_hms(18, 00, 0).unwrap(), ), ).execute().unwrap(); // Dump entire response: println!("{:#?}", time_zone); // Parsing example: use std::time::{SystemTime, UNIX_EPOCH}; let unix_timestamp = SystemTime::now().duration_since(UNIX_EPOCH).unwrap().as_secs(); println!("Time at your computer: {}", unix_timestamp); println!("Time in {}: {}", time_zone.time_zone_id.unwrap(), unix_timestamp as i64 + time_zone.dst_offset.unwrap() as i64 + time_zone.raw_offset.unwrap() as i64 );
Geolocation API
Google's Geolocation API seems to be offline. While the online
documentation is still available, and the API appears configurable through
the Google Cloud Platform console, the Geolocation API responds Status code
404 Not Found
with an empty body to all requests. This API cannot be
implemented until the server responds as expected.
To do:
- Convert explicit query validation to session types wherever reasonable.
- Places API
- Roads API
- Retry on Failure
- Automatic Rate Limiting

Modules
bounds | Contains the |
directions | The Directions API is a service that calculates directions between locations. You can search for directions for several modes of transportation, including transit, driving, walking, or cycling. |
distance_matrix | The Distance Matrix API is a service that provides travel distance and time for a matrix of origins and destinations, based on the recommended route between start and end points. |
elevation | The Elevation API provides elevation data for all locations on the surface of the earth, including depth locations on the ocean floor (which return negative values). |
geocoding | The Geocoding API is a service that provides geocoding and reverse geocoding of addresses. It can be used to convert a street address to geographic coordinates (latitude & longitude), or vice versa. |
language | Contains the |
latlng | Contains the |
place_type | Contains the |
region | Contains the |
time_zone | The Time Zone API provides time offset data for locations on the surface of the earth. You request the time zone information for a specific latitude/longitude pair and date. The API returns the name of that time zone, the time offset from UTC, and the daylight savings offset. |
Structs
Date | Calendar date. |
PrimitiveDateTime | Combined date and time. |
Time | The clock time within a given date. Nanosecond precision. |
