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.projects().regions_clusters_patch(...).doit() let r = hub.projects().regions_clusters_create(...).doit() let r = hub.projects().regions_operations_get(...).doit() let r = hub.projects().regions_clusters_delete(...).doit() let r = hub.projects().regions_clusters_diagnose(...).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-dataproc1 = "*"
A complete example
extern crate hyper; extern crate hyper_rustls; extern crate yup_oauth2 as oauth2; extern crate google_dataproc1 as dataproc1; use dataproc1::Cluster; use dataproc1::{Result, Error}; use std::default::Default; use oauth2::{Authenticator, DefaultAuthenticatorDelegate, ApplicationSecret, MemoryStorage}; use dataproc1::Dataproc; // 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 = Dataproc::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 = Cluster::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.projects().regions_clusters_patch(req, "projectId", "region", "clusterName") .update_mask("takimata") .graceful_decommission_timeout("justo") .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.

ProjectRegionOperationCancelCall |
Starts asynchronous cancellation on a long-running operation. The server makes a best effort to cancel the operation, but success is not guaranteed. If the server doesn't support this method, it returns google.rpc.Code.UNIMPLEMENTED. Clients can use Operations.GetOperation or other methods to check whether the cancellation succeeded or whether the operation completed despite cancellation. On successful cancellation, the operation is not deleted; instead, it becomes an operation with an Operation.error value with a google.rpc.Status.code of 1, corresponding to Code.CANCELLED. |
ProjectRegionOperationDeleteCall |
Deletes a long-running operation. This method indicates that the client is no longer interested in the operation result. It does not cancel the operation. If the server doesn't support this method, it returns google.rpc.Code.UNIMPLEMENTED. |
ProjectRegionOperationGetCall |
Gets the latest state of a long-running operation. Clients can use this method to poll the operation result at intervals as recommended by the API service. |
ProjectRegionOperationListCall |
Lists operations that match the specified filter in the request. If the server doesn't support this method, it returns UNIMPLEMENTED.NOTE: the name binding allows API services to override the binding to use different resource name schemes, such as users//operations. To override the binding, API services can add a binding such as "/v1/{name=users/}/operations" to their service configuration. For backwards compatibility, the default name includes the operations collection id, however overriding users must ensure the name binding is the parent resource, without the operations collection id. |

SparkSqlJob |
A Cloud Dataproc job for running Apache Spark SQL (http://spark.apache.org/sql/) queries. |
Status |
The Status type defines a logical error model that is suitable for different programming environments, including REST APIs and RPC APIs. It is used by gRPC (https://github.com/grpc). The error model is designed to be: Simple to use and understand for most users Flexible enough to meet unexpected needsOverviewThe Status message contains three pieces of data: error code, error message, and error details. The error code should be an enum value of google.rpc.Code, but it may accept additional error codes if needed. The error message should be a developer-facing English message that helps developers understand and resolve the error. If a localized user-facing error message is needed, put the localized message in the error details or localize it in the client. The optional error details may contain arbitrary information about the error. There is a predefined set of error detail types in the package google.rpc that can be used for common error conditions.Language mappingThe Status message is the logical representation of the error model, but it is not necessarily the actual wire format. When the Status message is exposed in different client libraries and different wire protocols, it can be mapped differently. For example, it will likely be mapped to some exceptions in Java, but more likely mapped to some error codes in C.Other usesThe error model and the Status message can be used in a variety of environments, either with or without APIs, to provide a consistent developer experience across different environments.Example uses of this error model include: Partial errors. If a service needs to return partial errors to the client, it may embed the Status in the normal response to indicate the partial errors. Workflow errors. A typical workflow has multiple steps. Each step may have a Status message for error reporting. Batch operations. If a client uses batch request and batch response, the Status message should be used directly inside batch response, one for each error sub-response. Asynchronous operations. If an API call embeds asynchronous operation results in its response, the status of those operations should be represented directly using the Status message. Logging. If some API errors are stored in logs, the message Status could be used directly after any stripping needed for security/privacy reasons. |
