The `google-gkehub1` library allows access to all features of the *Google GKE Hub* service. This documentation was generated from *GKE Hub* crate version *5.0.3+20230106*, where *20230106* is the exact revision of the *gkehub:v1* schema built by the [mako](http://www.makotemplates.org/) code generator *v5.0.3*. Everything else about the *GKE Hub* *v1* API can be found at the [official documentation site](https://cloud.google.com/anthos/multicluster-management/connect/registering-a-cluster). # Features Handle the following *Resources* with ease from the central [hub](https://docs.rs/google-gkehub1/5.0.3+20230106/google_gkehub1/GKEHub) ... * projects * [*locations features create*](https://docs.rs/google-gkehub1/5.0.3+20230106/google_gkehub1/api::ProjectLocationFeatureCreateCall), [*locations features delete*](https://docs.rs/google-gkehub1/5.0.3+20230106/google_gkehub1/api::ProjectLocationFeatureDeleteCall), [*locations features get*](https://docs.rs/google-gkehub1/5.0.3+20230106/google_gkehub1/api::ProjectLocationFeatureGetCall), [*locations features get iam policy*](https://docs.rs/google-gkehub1/5.0.3+20230106/google_gkehub1/api::ProjectLocationFeatureGetIamPolicyCall), [*locations features list*](https://docs.rs/google-gkehub1/5.0.3+20230106/google_gkehub1/api::ProjectLocationFeatureListCall), [*locations features patch*](https://docs.rs/google-gkehub1/5.0.3+20230106/google_gkehub1/api::ProjectLocationFeaturePatchCall), [*locations features set iam policy*](https://docs.rs/google-gkehub1/5.0.3+20230106/google_gkehub1/api::ProjectLocationFeatureSetIamPolicyCall), [*locations features test iam permissions*](https://docs.rs/google-gkehub1/5.0.3+20230106/google_gkehub1/api::ProjectLocationFeatureTestIamPermissionCall), [*locations get*](https://docs.rs/google-gkehub1/5.0.3+20230106/google_gkehub1/api::ProjectLocationGetCall), [*locations list*](https://docs.rs/google-gkehub1/5.0.3+20230106/google_gkehub1/api::ProjectLocationListCall), [*locations memberships create*](https://docs.rs/google-gkehub1/5.0.3+20230106/google_gkehub1/api::ProjectLocationMembershipCreateCall), [*locations memberships delete*](https://docs.rs/google-gkehub1/5.0.3+20230106/google_gkehub1/api::ProjectLocationMembershipDeleteCall), [*locations memberships generate connect manifest*](https://docs.rs/google-gkehub1/5.0.3+20230106/google_gkehub1/api::ProjectLocationMembershipGenerateConnectManifestCall), [*locations memberships get*](https://docs.rs/google-gkehub1/5.0.3+20230106/google_gkehub1/api::ProjectLocationMembershipGetCall), [*locations memberships get iam policy*](https://docs.rs/google-gkehub1/5.0.3+20230106/google_gkehub1/api::ProjectLocationMembershipGetIamPolicyCall), [*locations memberships list*](https://docs.rs/google-gkehub1/5.0.3+20230106/google_gkehub1/api::ProjectLocationMembershipListCall), [*locations memberships patch*](https://docs.rs/google-gkehub1/5.0.3+20230106/google_gkehub1/api::ProjectLocationMembershipPatchCall), [*locations memberships set iam policy*](https://docs.rs/google-gkehub1/5.0.3+20230106/google_gkehub1/api::ProjectLocationMembershipSetIamPolicyCall), [*locations memberships test iam permissions*](https://docs.rs/google-gkehub1/5.0.3+20230106/google_gkehub1/api::ProjectLocationMembershipTestIamPermissionCall), [*locations operations cancel*](https://docs.rs/google-gkehub1/5.0.3+20230106/google_gkehub1/api::ProjectLocationOperationCancelCall), [*locations operations delete*](https://docs.rs/google-gkehub1/5.0.3+20230106/google_gkehub1/api::ProjectLocationOperationDeleteCall), [*locations operations get*](https://docs.rs/google-gkehub1/5.0.3+20230106/google_gkehub1/api::ProjectLocationOperationGetCall) and [*locations operations list*](https://docs.rs/google-gkehub1/5.0.3+20230106/google_gkehub1/api::ProjectLocationOperationListCall) # Structure of this Library The API is structured into the following primary items: * **[Hub](https://docs.rs/google-gkehub1/5.0.3+20230106/google_gkehub1/GKEHub)** * a central object to maintain state and allow accessing all *Activities* * creates [*Method Builders*](https://docs.rs/google-gkehub1/5.0.3+20230106/google_gkehub1/client::MethodsBuilder) which in turn allow access to individual [*Call Builders*](https://docs.rs/google-gkehub1/5.0.3+20230106/google_gkehub1/client::CallBuilder) * **[Resources](https://docs.rs/google-gkehub1/5.0.3+20230106/google_gkehub1/client::Resource)** * primary types that you can apply *Activities* to * a collection of properties and *Parts* * **[Parts](https://docs.rs/google-gkehub1/5.0.3+20230106/google_gkehub1/client::Part)** * a collection of properties * never directly used in *Activities* * **[Activities](https://docs.rs/google-gkehub1/5.0.3+20230106/google_gkehub1/client::CallBuilder)** * 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: ```Rust,ignore let r = hub.resource().activity(...).doit().await ``` Or specifically ... ```ignore let r = hub.projects().locations_features_create(...).doit().await let r = hub.projects().locations_features_delete(...).doit().await let r = hub.projects().locations_features_patch(...).doit().await let r = hub.projects().locations_memberships_create(...).doit().await let r = hub.projects().locations_memberships_delete(...).doit().await let r = hub.projects().locations_memberships_patch(...).doit().await let r = hub.projects().locations_operations_get(...).doit().await ``` The `resource()` and `activity(...)` calls create [builders][builder-pattern]. 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][builder-pattern] 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: ```toml [dependencies] google-gkehub1 = "*" serde = "^1.0" serde_json = "^1.0" ``` ## A complete example ```Rust extern crate hyper; extern crate hyper_rustls; extern crate google_gkehub1 as gkehub1; use gkehub1::api::Feature; use gkehub1::{Result, Error}; use std::default::Default; use gkehub1::{GKEHub, oauth2, hyper, hyper_rustls, chrono, FieldMask}; // Get an ApplicationSecret instance by some means. It contains the `client_id` and // `client_secret`, among other things. let secret: oauth2::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 = oauth2::InstalledFlowAuthenticator::builder( secret, oauth2::InstalledFlowReturnMethod::HTTPRedirect, ).build().await.unwrap(); let mut hub = GKEHub::new(hyper::Client::builder().build(hyper_rustls::HttpsConnectorBuilder::new().with_native_roots().https_or_http().enable_http1().build()), 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 = Feature::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().locations_features_create(req, "parent") .request_id("magna") .feature_id("no") .doit().await; 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::Io(_) |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](https://docs.rs/google-gkehub1/5.0.3+20230106/google_gkehub1/client::Result) enumeration as return value of the doit() methods, or handed as possibly intermediate results to either the [Hub Delegate](https://docs.rs/google-gkehub1/5.0.3+20230106/google_gkehub1/client::Delegate), or the [Authenticator Delegate](https://docs.rs/yup-oauth2/*/yup_oauth2/trait.AuthenticatorDelegate.html). 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](https://docs.rs/google-gkehub1/5.0.3+20230106/google_gkehub1/client::Result), should be read by you to obtain the media. If such a method also supports a [Response Result](https://docs.rs/google-gkehub1/5.0.3+20230106/google_gkehub1/client::ResponseResult), 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](https://docs.rs/google-gkehub1/5.0.3+20230106/google_gkehub1/client::Delegate) to the [Method Builder](https://docs.rs/google-gkehub1/5.0.3+20230106/google_gkehub1/client::CallBuilder) 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](https://docs.rs/google-gkehub1/5.0.3+20230106/google_gkehub1/client::Delegate) 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 [encodable](https://docs.rs/google-gkehub1/5.0.3+20230106/google_gkehub1/client::RequestValue) and [decodable](https://docs.rs/google-gkehub1/5.0.3+20230106/google_gkehub1/client::ResponseResult) via *json*. Optionals are used to indicate that partial requests are responses are valid. Most optionals are are considered [Parts](https://docs.rs/google-gkehub1/5.0.3+20230106/google_gkehub1/client::Part) 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](https://docs.rs/google-gkehub1/5.0.3+20230106/google_gkehub1/client::CallBuilder), 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][wiki-pod] are handed by copy * strings are passed as `&str` * [request values](https://docs.rs/google-gkehub1/5.0.3+20230106/google_gkehub1/client::RequestValue) are moved Arguments will always be copied or cloned into the builder, to make them independent of their original life times.
