Structure of this Library
The API is structured into the following primary items:
- Hub
- a central object to maintain state and allow accessing all Activities
- creates Method Builders which in turn allow access to individual Call Builders
- Resources
- primary types that you can apply Activities to
- a collection of properties and Parts
- Parts
- a collection of properties
- never directly used in Activities
- Activities
- operations to apply to Resources
All structures are marked with applicable traits to further categorize them and ease browsing.
Generally speaking, you can invoke Activities like this:
let r = hub.resource().activity(...).doit()
Or specifically ...
let r = hub.trips().search(...).doit()
The resource()
and activity(...)
calls create builders. The second one dealing with Activities
supports various methods to configure the impending operation (not shown here). It is made such that all required arguments have to be
specified right away (i.e. (...)
), whereas all optional ones can be build up as desired.
The doit()
method performs the actual communication with the server and returns the respective result.
Usage
Setting up your Project
To use this library, you would put the following lines into your Cargo.toml
file:
[dependencies]
google-qpxexpress1 = "*"
A complete example
extern crate hyper; extern crate hyper_rustls; extern crate yup_oauth2 as oauth2; extern crate google_qpxexpress1 as qpxexpress1; use qpxexpress1::TripsSearchRequest; use qpxexpress1::{Result, Error}; use std::default::Default; use oauth2::{Authenticator, DefaultAuthenticatorDelegate, ApplicationSecret, MemoryStorage}; use qpxexpress1::QPXExpress; // Get an ApplicationSecret instance by some means. It contains the `client_id` and // `client_secret`, among other things. let secret: ApplicationSecret = Default::default(); // Instantiate the authenticator. It will choose a suitable authentication flow for you, // unless you replace `None` with the desired Flow. // Provide your own `AuthenticatorDelegate` to adjust the way it operates and get feedback about // what's going on. You probably want to bring in your own `TokenStorage` to persist tokens and // retrieve them from storage. let auth = Authenticator::new(&secret, DefaultAuthenticatorDelegate, hyper::Client::with_connector(hyper::net::HttpsConnector::new(hyper_rustls::TlsClient::new())), <MemoryStorage as Default>::default(), None); let mut hub = QPXExpress::new(hyper::Client::with_connector(hyper::net::HttpsConnector::new(hyper_rustls::TlsClient::new())), auth); // As the method needs a request, you would usually fill it with the desired information // into the respective structure. Some of the parts shown here might not be applicable ! // Values shown here are possibly random and not representative ! let mut req = TripsSearchRequest::default(); // You can configure optional parameters by calling the respective setters at will, and // execute the final call using `doit()`. // Values shown here are possibly random and not representative ! let result = hub.trips().search(req) .doit(); match result { Err(e) => match e { // The Error enum provides details about what exactly happened. // You can also just use its `Debug`, `Display` or `Error` traits Error::HttpError(_) |Error::MissingAPIKey |Error::MissingToken(_) |Error::Cancelled |Error::UploadSizeLimitExceeded(_, _) |Error::Failure(_) |Error::BadRequest(_) |Error::FieldClash(_) |Error::JsonDecodeError(_, _) => println!("{}", e), }, Ok(res) => println!("Success: {:?}", res), }
Handling Errors
All errors produced by the system are provided either as Result enumeration as return value of the doit() methods, or handed as possibly intermediate results to either the Hub Delegate, or the Authenticator Delegate.
When delegates handle errors or intermediate values, they may have a chance to instruct the system to retry. This makes the system potentially resilient to all kinds of errors.
Uploads and Downloads
If a method supports downloads, the response body, which is part of the Result, should be
read by you to obtain the media.
If such a method also supports a Response Result, it will return that by default.
You can see it as meta-data for the actual media. To trigger a media download, you will have to set up the builder by making
this call: .param("alt", "media")
.
Methods supporting uploads can do so using up to 2 different protocols:
simple and resumable. The distinctiveness of each is represented by customized
doit(...)
methods, which are then named upload(...)
and upload_resumable(...)
respectively.
Customization and Callbacks
You may alter the way an doit()
method is called by providing a delegate to the
Method Builder before making the final doit()
call.
Respective methods will be called to provide progress information, as well as determine whether the system should
retry on failure.
The delegate trait is default-implemented, allowing you to customize it with minimal effort.
Optional Parts in Server-Requests
All structures provided by this library are made to be enocodable and decodable via json. Optionals are used to indicate that partial requests are responses are valid. Most optionals are are considered Parts which are identifiable by name, which will be sent to the server to indicate either the set parts of the request or the desired parts in the response.
Builder Arguments
Using method builders, you are able to prepare an action call by repeatedly calling it's methods. These will always take a single argument, for which the following statements are true.
- PODs are handed by copy
- strings are passed as
&str
- request values are moved
Arguments will always be copied or cloned into the builder, to make them independent of their original life times.
Structs
AircraftData |
The make, model, and type of an aircraft. |
AirportData |
An airport. |
BagDescriptor |
Information about an item of baggage. |
CarrierData |
Information about a carrier (ie. an airline, bus line, railroad, etc) that might be useful to display to an end-user. |
CityData |
Information about a city that might be useful to an end-user; typically the city of an airport. |
Data |
Detailed information about components found in the solutions of this response, including a trip's airport, city, taxes, airline, and aircraft. |
DefaultDelegate |
A delegate with a conservative default implementation, which is used if no other delegate is set. |
ErrorResponse |
A utility to represent detailed errors we might see in case there are BadRequests. The latter happen if the sent parameters or request structures are unsound |
FareInfo |
Complete information about a fare used in the solution to a low-fare search query. In the airline industry a fare is a price an airline charges for one-way travel between two points. A fare typically contains a carrier code, two city codes, a price, and a fare basis. (A fare basis is a one-to-eight character alphanumeric code used to identify a fare.) |
FlightInfo |
A flight is a sequence of legs with the same airline carrier and flight number. (A leg is the smallest unit of travel, in the case of a flight a takeoff immediately followed by a landing at two set points on a particular carrier with a particular flight number.) The naive view is that a flight is scheduled travel of an aircraft between two points, with possibly intermediate stops, but carriers will frequently list flights that require a change of aircraft between legs. |
FreeBaggageAllowance |
Information about free baggage allowed on one segment of a trip. |
LegInfo |
Information about a leg. (A leg is the smallest unit of travel, in the case of a flight a takeoff immediately followed by a landing at two set points on a particular carrier with a particular flight number.) |
MethodInfo |
Contains information about an API request. |
MultiPartReader |
Provides a |
PassengerCounts |
The number and type of passengers. Unfortunately the definition of an infant, child, adult, and senior citizen varies across carriers and reservation systems. |
PricingInfo |
The price of one or more travel segments. The currency used to purchase tickets is usually determined by the sale/ticketing city or the sale/ticketing country, unless none are specified, in which case it defaults to that of the journey origin country. |
QPXExpress |
Central instance to access all QPXExpress related resource activities |
SegmentInfo |
Details of a segment of a flight; a segment is one or more consecutive legs on the same flight. For example a hypothetical flight ZZ001, from DFW to OGG, would have one segment with two legs: DFW to HNL (leg 1), HNL to OGG (leg 2), and DFW to OGG (legs 1 and 2). |
SegmentPricing |
The price of this segment. |
SliceInfo |
Information about a slice. A slice represents a traveller's intent, the portion of a low-fare search corresponding to a traveler's request to get between two points. One-way journeys are generally expressed using 1 slice, round-trips using 2. For example, if a traveler specifies the following trip in a user interface: | Origin | Destination | Departure Date | | BOS | LAX | March 10, 2007 | | LAX | SYD | March 17, 2007 | | SYD | BOS | March 22, 2007 | then this is a three slice trip. |
SliceInput |
Criteria a desired slice must satisfy. |
TaxData |
Tax data. |
TaxInfo |
Tax information. |
TimeOfDayRange |
Two times in a single day defining a time range. |
TripMethods |
A builder providing access to all methods supported on trip resources.
It is not used directly, but through the |
TripOption |
Trip information. |
TripOptionsRequest |
A QPX Express search request, which will yield one or more solutions. |
TripOptionsResponse |
A QPX Express search response. |
TripSearchCall |
Returns a list of flights. |
TripsSearchRequest |
A QPX Express search request. |
TripsSearchResponse |
A QPX Express search response. |
Enums
Error |
Traits
CallBuilder |
Identifies types which represent builders for a particular resource method |
Delegate |
A trait specifying functionality to help controlling any request performed by the API. The trait has a conservative default implementation. |
Hub |
Identifies the Hub. There is only one per library, this trait is supposed to make intended use more explicit. The hub allows to access all resource methods more easily. |
MethodsBuilder |
Identifies types for building methods of a particular resource type |
NestedType |
Identifies types which are only used by other types internally. They have no special meaning, this trait just marks them for completeness. |
Part |
Identifies types which are only used as part of other types, which
usually are carrying the |
ReadSeek |
A utility to specify reader types which provide seeking capabilities too |
RequestValue |
Identifies types which are used in API requests. |
Resource |
Identifies types which can be inserted and deleted. Types with this trait are most commonly used by clients of this API. |
ResponseResult |
Identifies types which are used in API responses. |
ToParts |
A trait for all types that can convert themselves into a parts string |
Functions
remove_json_null_values |
Type Definitions
Result |
A universal result type used as return for all calls. |
