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.apps().services_versions_create(...).doit()
let r = hub.apps().patch(...).doit()
let r = hub.apps().services_versions_instances_debug(...).doit()
let r = hub.apps().create(...).doit()
let r = hub.apps().services_versions_instances_delete(...).doit()
let r = hub.apps().services_versions_patch(...).doit()
let r = hub.apps().operations_get(...).doit()
let r = hub.apps().repair(...).doit()
let r = hub.apps().services_versions_delete(...).doit()
let r = hub.apps().services_patch(...).doit()
let r = hub.apps().services_delete(...).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-appengine1 = "*"

A complete example

extern crate hyper;
extern crate yup_oauth2 as oauth2;
extern crate google_appengine1 as appengine1;
use appengine1::DebugInstanceRequest;
use appengine1::{Result, Error};
use std::default::Default;
use oauth2::{Authenticator, DefaultAuthenticatorDelegate, ApplicationSecret, MemoryStorage};
use appengine1::Appengine;
 
// 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::new(),
                              <MemoryStorage as Default>::default(), None);
let mut hub = Appengine::new(hyper::Client::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 = DebugInstanceRequest::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.apps().services_versions_instances_debug(req, "appsId", "servicesId", "versionsId", "instancesId")
             .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.

Arguments will always be copied or cloned into the builder, to make them independent of their original life times.

Structs

ApiConfigHandler

Google Cloud Endpoints (https://cloud.google.com/appengine/docs/python/endpoints/) configuration for API handlers.

ApiEndpointHandler

Uses Google Cloud Endpoints to handle requests.

AppCreateCall

Creates an App Engine application for a Google Cloud Platform project. This requires a project that excludes an App Engine application. For details about creating a project without an application, see the Google Cloud Resource Manager create project topic (https://cloud.google.com/resource-manager/docs/creating-project).

AppGetCall

Gets information about an application.

AppLocationGetCall

Get information about a location.

Lists information about the supported locations for this service.

AppMethods

A builder providing access to all methods supported on app resources. It is not used directly, but through the Appengine hub.

AppOperationGetCall

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.

AppOperationListCall

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 below allows API services to override the binding to use different resource name schemes, such as users/*/operations.

AppPatchCall

Updates the specified Application resource. You can update the following fields: auth_domain (https://cloud.google.com/appengine/docs/admin-api/reference/rest/v1/apps#Application.FIELDS.auth_domain) default_cookie_expiration (https://cloud.google.com/appengine/docs/admin-api/reference/rest/v1/apps#Application.FIELDS.default_cookie_expiration)

AppServiceVersionInstanceDebugCall

Enables debugging on a VM instance. This allows you to use the SSH command to connect to the virtual machine where the instance lives. While in "debug mode", the instance continues to serve live traffic. You should delete the instance when you are done debugging and then allow the system to take over and determine if another instance should be started.Only applicable for instances in App Engine flexible environment.

Appengine

Central instance to access all Appengine related resource activities

Application

An Application resource contains the top-level configuration of an App Engine application.

AutomaticScaling

Automatic scaling is based on request rate, response latencies, and other application metrics.

BasicScaling

A service with basic scaling will create an instance when the application receives a request. The instance will be turned down when the app becomes idle. Basic scaling is ideal for work that is intermittent or driven by user activity.

ContainerInfo

Docker image that is used to start a VM container for the version you deploy.

CpuUtilization

Target scaling by CPU usage.

DebugInstanceRequest

Request message for Instances.DebugInstance.

DefaultDelegate

A delegate with a conservative default implementation, which is used if no other delegate is set.

Deployment

Code and application artifacts used to deploy a version to App Engine.

DiskUtilization

Target scaling by disk usage. Only applicable for VM runtimes.

EndpointsApiService

Cloud Endpoints (https://cloud.google.com/endpoints) configuration. The Endpoints API Service provides tooling for serving Open API and gRPC endpoints via an NGINX proxy.The fields here refer to the name and configuration id of a "service" resource in the Service Management API (https://cloud.google.com/service-management/overview).

ErrorHandler

Custom static error page to be served when an error occurs.

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

FileInfo

Single source file that is part of the version to be deployed. Each source file that is deployed must be specified separately.

HealthCheck

Health checking configuration for VM instances. Unhealthy instances are killed and replaced with new instances. Only applicable for instances in App Engine flexible environment.

Instance

An Instance resource is the computing unit that App Engine uses to automatically scale an application.

Library

Third-party Python runtime library that is required by the application.

ListInstancesResponse

Response message for Instances.ListInstances.

The response message for LocationService.ListLocations.

ListOperationsResponse

The response message for Operations.ListOperations.

ListServicesResponse

Response message for Services.ListServices.

ListVersionsResponse

Response message for Versions.ListVersions.

Location

A resource that represents Google Cloud Platform location.

ManualScaling

A service with manual scaling runs continuously, allowing you to perform complex initialization and rely on the state of its memory over time.

MethodInfo

Contains information about an API request.

MultiPartReader

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.

Network

Extra network settings. Only applicable for VM runtimes.

NetworkUtilization

Target scaling by network usage. Only applicable for VM runtimes.

Operation

This resource represents a long-running operation that is the result of a network API call.

RepairApplicationRequest

Request message for 'Applications.RepairApplication'.

RequestUtilization

Target scaling by request utilization. Only applicable for VM runtimes.

Resources

Machine resources for a version.

ScriptHandler

Executes a script to handle the request that matches the URL pattern.

Service

A Service resource is a logical component of an application that can share state and communicate in a secure fashion with other services. For example, an application that handles customer requests might include separate services to handle tasks such as backend data analysis or API requests from mobile devices. Each service has a collection of versions that define a specific set of code used to implement the functionality of that service.

StaticFilesHandler

Files served directly to the user for a given URL, such as images, CSS stylesheets, or JavaScript source files. Static file handlers describe which files in the application directory are static files, and which URLs serve them.

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 which 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 purpose. 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.

TrafficSplit

Traffic routing configuration for versions within a single service. Traffic splits define how traffic directed to the service is assigned to versions.

UrlDispatchRule

Rules to match an HTTP request and dispatch that request to a service.

UrlMap

URL pattern and description of how the URL should be handled. App Engine can handle URLs by executing application code or by serving static files uploaded with the version, such as images, CSS, or JavaScript.

Version

A Version resource is a specific set of source code and configuration files that are deployed into a service.

Volume

Volumes mounted within the app container. Only applicable for VM runtimes.

ZipInfo

The zip file information for a zip deployment.

Enums

Error
Scope

Identifies the an OAuth2 authorization scope. A scope is needed when requesting an authorization token.
