§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().models_versions_create(...).doit()
let r = hub.projects().models_versions_patch(...).doit()
let r = hub.projects().operations_get(...).doit()
let r = hub.projects().models_versions_delete(...).doit()
let r = hub.projects().models_delete(...).doit()
let r = hub.projects().models_patch(...).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-ml1 = "*"
§A complete example
extern crate hyper;
extern crate hyper_rustls;
extern crate yup_oauth2 as oauth2;
extern crate google_ml1 as ml1;
use ml1::GoogleCloudMlV1__Version;
use ml1::{Result, Error};
use std::default::Default;
use oauth2::{Authenticator, DefaultAuthenticatorDelegate, ApplicationSecret, MemoryStorage};
use ml1::CloudMachineLearningEngine;
// 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 = CloudMachineLearningEngine::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 = GoogleCloudMlV1__Version::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().models_versions_patch(req, "name")
.update_mask("sed")
.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§
- Central instance to access all CloudMachineLearningEngine related resource activities
- A delegate with a conservative default implementation, which is used if no other delegate is set.
- 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
- Message that represents an arbitrary HTTP body. It should only be used for payload formats that can’t be represented as JSON, such as raw binary or an HTML page.
- An observed value of a metric.
- Options for automatically scaling a model.
- Request message for the CancelJob method.
- There is no detailed description.
- Returns service account information associated with a project.
- Represents the result of a single hyperparameter tuning trial from a training job. The TrainingOutput object that is returned on successful completion of a training job with hyperparameter tuning includes a list of HyperparameterOutput objects, one for each successful trial.
- Represents a set of hyperparameters to optimize.
- Represents a training or prediction job.
- Response message for the ListJobs method.
- There is no detailed description.
- Response message for the ListModels method.
- Response message for the ListVersions method.
- There is no detailed description.
- Options for manually scaling a model.
- Represents a machine learning solution.
- Represents a single hyperparameter to optimize.
- Request for predictions to be issued against a trained model.
- Represents input parameters for a prediction job.
- Represents results of a prediction job.
- Request message for the SetDefaultVersion request.
- Represents input parameters for a training job.
- Represents results of a training job. Output only.
- Represents a version of the model.
- Specifies the audit configuration for a service. The configuration determines which permission types are logged, and what identities, if any, are exempted from logging. An AuditConfig must have one or more AuditLogConfigs.
- Provides the configuration for logging a type of permissions. Example:
- Associates
members
with arole
. - Defines an Identity and Access Management (IAM) policy. It is used to specify access control policies for Cloud Platform resources.
- Request message for
SetIamPolicy
method. - Request message for
TestIamPermissions
method. - Response message for
TestIamPermissions
method. - The response message for Operations.ListOperations.
- This resource represents a long-running operation that is the result of a network API call.
- A generic empty message that you can re-use to avoid defining duplicated empty messages in your APIs. A typical example is to use it as the request or the response type of an API method. For instance:
- 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. The error model is designed to be: - Represents an expression text. Example:
- Contains information about an API request.
- Provides a
Read
interface that converts multiple parts into the protocol identified by RFC2387. Note: This implementation is just as rich as it needs to be to perform uploads to google APIs, and might not be a fully-featured implementation. - Get the service account information associated with your project. You need this information in order to grant the service account persmissions for the Google Cloud Storage location where you put your model training code for training the model with Google Cloud Machine Learning.
- Cancels a running job.
- Creates a training or a batch prediction job.
- Describes a job.
- Gets the access control policy for a resource. Returns an empty policy if the resource exists and does not have a policy set.
- Lists the jobs in the project.
- Updates a specific job resource.
- Sets the access control policy on the specified resource. Replaces any existing policy.
- Returns permissions that a caller has on the specified resource. If the resource does not exist, this will return an empty set of permissions, not a NOT_FOUND error.
- Get the complete list of CMLE capabilities in a location, along with their location-specific properties.
- List all locations that provides at least one type of CMLE capability.
- A builder providing access to all methods supported on project resources. It is not used directly, but through the
CloudMachineLearningEngine
hub. - Creates a model which will later contain one or more versions.
- Deletes a model.
- Gets information about a model, including its name, the description (if set), and the default version (if at least one version of the model has been deployed).
- Gets the access control policy for a resource. Returns an empty policy if the resource exists and does not have a policy set.
- Lists the models in a project.
- Updates a specific model resource.
- Sets the access control policy on the specified resource. Replaces any existing policy.
- Returns permissions that a caller has on the specified resource. If the resource does not exist, this will return an empty set of permissions, not a NOT_FOUND error.
- Creates a new version of a model from a trained TensorFlow model.
- Deletes a model version.
- Gets information about a model version.
- Gets basic information about all the versions of a model.
- Updates the specified Version resource.
- Designates a version to be the default for the model.
- 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 toCode.CANCELLED
. - 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
. - 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.
- Lists operations that match the specified filter in the request. If the server doesn’t support this method, it returns
UNIMPLEMENTED
. - Performs prediction on the data in the request. Cloud ML Engine implements a custom
predict
verb on top of an HTTP POST method. For details of the format, see the guide to the predict request format.
Enums§
- Identifies the an OAuth2 authorization scope. A scope is needed when requesting an authorization token.
Traits§
- Identifies types which represent builders for a particular resource method
- A trait specifying functionality to help controlling any request performed by the API. The trait has a conservative default implementation.
- 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.
- Identifies types for building methods of a particular resource type
- Identifies types which are only used by other types internally. They have no special meaning, this trait just marks them for completeness.
- Identifies types which are only used as part of other types, which usually are carrying the
Resource
trait. - A utility to specify reader types which provide seeking capabilities too
- Identifies types which are used in API requests.
- Identifies types which can be inserted and deleted. Types with this trait are most commonly used by clients of this API.
- Identifies types which are used in API responses.
- A trait for all types that can convert themselves into a parts string
Functions§
Type Aliases§
- A universal result type used as return for all calls.
