The `google-retail2` library allows access to all features of the *Google Cloud Retail* service.
This documentation was generated from *Cloud Retail* crate version *5.0.4+20240222*, where *20240222* is the exact revision of the *retail:v2* schema built by the [mako](http://www.makotemplates.org/) code generator *v5.0.4*.
Everything else about the *Cloud Retail* *v2* API can be found at the
[official documentation site](https://cloud.google.com/recommendations).

# Structure of this Library
The API is structured into the following primary items:
* **[Hub](https://docs.rs/google-retail2/5.0.4+20240222/google_retail2/CloudRetail)**
* a central object to maintain state and allow accessing all *Activities*
* creates [*Method Builders*](https://docs.rs/google-retail2/5.0.4+20240222/google_retail2/client::MethodsBuilder) which in turn
allow access to individual [*Call Builders*](https://docs.rs/google-retail2/5.0.4+20240222/google_retail2/client::CallBuilder)
* **[Resources](https://docs.rs/google-retail2/5.0.4+20240222/google_retail2/client::Resource)**
* primary types that you can apply *Activities* to
* a collection of properties and *Parts*
* **[Parts](https://docs.rs/google-retail2/5.0.4+20240222/google_retail2/client::Part)**
* a collection of properties
* never directly used in *Activities*
* **[Activities](https://docs.rs/google-retail2/5.0.4+20240222/google_retail2/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_catalogs_branches_operations_get(...).doit().await
let r = hub.projects().locations_catalogs_branches_products_add_fulfillment_places(...).doit().await
let r = hub.projects().locations_catalogs_branches_products_add_local_inventories(...).doit().await
let r = hub.projects().locations_catalogs_branches_products_import(...).doit().await
let r = hub.projects().locations_catalogs_branches_products_purge(...).doit().await
let r = hub.projects().locations_catalogs_branches_products_remove_fulfillment_places(...).doit().await
let r = hub.projects().locations_catalogs_branches_products_remove_local_inventories(...).doit().await
let r = hub.projects().locations_catalogs_branches_products_set_inventory(...).doit().await
let r = hub.projects().locations_catalogs_completion_data_import(...).doit().await
let r = hub.projects().locations_catalogs_models_create(...).doit().await
let r = hub.projects().locations_catalogs_models_tune(...).doit().await
let r = hub.projects().locations_catalogs_operations_get(...).doit().await
let r = hub.projects().locations_catalogs_user_events_import(...).doit().await
let r = hub.projects().locations_catalogs_user_events_purge(...).doit().await
let r = hub.projects().locations_catalogs_user_events_rejoin(...).doit().await
let r = hub.projects().locations_catalogs_export_analytics_metrics(...).doit().await
let r = hub.projects().locations_operations_get(...).doit().await
let r = hub.projects().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-retail2 = "*"
serde = "^1.0"
serde_json = "^1.0"
```
## A complete example
```Rust
extern crate hyper;
extern crate hyper_rustls;
extern crate google_retail2 as retail2;
use retail2::api::GoogleCloudRetailV2Model;
use retail2::{Result, Error};
use std::default::Default;
use retail2::{CloudRetail, 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 = CloudRetail::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 = GoogleCloudRetailV2Model::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_catalogs_models_create(req, "parent")
.dry_run(true)
.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-retail2/5.0.4+20240222/google_retail2/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-retail2/5.0.4+20240222/google_retail2/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-retail2/5.0.4+20240222/google_retail2/client::Result), should be
read by you to obtain the media.
If such a method also supports a [Response Result](https://docs.rs/google-retail2/5.0.4+20240222/google_retail2/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-retail2/5.0.4+20240222/google_retail2/client::Delegate) to the
[Method Builder](https://docs.rs/google-retail2/5.0.4+20240222/google_retail2/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-retail2/5.0.4+20240222/google_retail2/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-retail2/5.0.4+20240222/google_retail2/client::RequestValue) and
[decodable](https://docs.rs/google-retail2/5.0.4+20240222/google_retail2/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-retail2/5.0.4+20240222/google_retail2/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-retail2/5.0.4+20240222/google_retail2/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-retail2/5.0.4+20240222/google_retail2/client::RequestValue) are moved
Arguments will always be copied or cloned into the builder, to make them independent of their original life times.
