Crate google_runtimeconfig1_beta1[][src]

This documentation was generated from Cloud RuntimeConfig crate version 1.0.8+20181008, where 20181008 is the exact revision of the runtimeconfig:v1beta1 schema built by the mako code generator v1.0.8.

Everything else about the Cloud RuntimeConfig v1_beta1 API can be found at the official documentation site. The original source code is on github.

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 ...

This example is not tested
let r = hub.projects().configs_variables_watch(...).doit()
let r = hub.projects().configs_variables_get(...).doit()
let r = hub.projects().configs_variables_update(...).doit()
let r = hub.projects().configs_variables_create(...).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.


Setting up your Project

To use this library, you would put the following lines into your Cargo.toml file:

google-runtimeconfig1_beta1 = "*"
# This project intentionally uses an old version of Hyper. See
# for more
# information.
hyper = "^0.10"
hyper-rustls = "^0.6"
serde = "^1.0"
serde_json = "^1.0"
yup-oauth2 = "^1.0"

A complete example

extern crate hyper;
extern crate hyper_rustls;
extern crate yup_oauth2 as oauth2;
extern crate google_runtimeconfig1_beta1 as runtimeconfig1_beta1;
use runtimeconfig1_beta1::Variable;
use runtimeconfig1_beta1::{Result, Error};
use std::default::Default;
use oauth2::{Authenticator, DefaultAuthenticatorDelegate, ApplicationSecret, MemoryStorage};
use runtimeconfig1_beta1::CloudRuntimeConfig;
// 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,
                              <MemoryStorage as Default>::default(), None);
let mut hub = CloudRuntimeConfig::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 = Variable::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().configs_variables_create(req, "parent")
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::UploadSizeLimitExceeded(_, _)
        |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.



Associates members with a role.


A Cardinality condition for the Waiter resource. A cardinality condition is met when the number of variables under a specified path prefix reaches a predefined number. For example, if you set a Cardinality condition where the path is set to /foo and the number of paths is set to 2, the following variables would meet the condition in a RuntimeConfig resource:


Central instance to access all CloudRuntimeConfig related resource activities


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


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 condition that a Waiter resource is waiting for.


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


Represents an expression text. Example:


ListConfigs() returns the following response. The order of returned objects is arbitrary; that is, it is not ordered in any particular way.


Response for the ListVariables() method.


Response for the ListWaiters() method. Order of returned waiter objects is arbitrary.


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.


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


Defines an Identity and Access Management (IAM) policy. It is used to specify access control policies for Cloud Platform resources.


Creates a new RuntimeConfig resource. The configuration name must be unique within project.


Deletes a RuntimeConfig resource.


Gets information about a RuntimeConfig resource.


Gets the access control policy for a resource. Returns an empty policy if the resource exists and does not have a policy set.


Lists all the RuntimeConfig resources within project.


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.


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.


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.


Updates a RuntimeConfig resource. The configuration must exist beforehand.


Creates a variable within the given configuration. You cannot create a variable with a name that is a prefix of an existing variable name, or a name that has an existing variable name as a prefix.


Deletes a variable or multiple variables.


Gets information about a single variable.


Lists variables within given a configuration, matching any provided filters. This only lists variable names, not the values, unless return_values is true, in which case only variables that user has IAM permission to GetVariable will be returned.


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.


Updates an existing variable with a new value.


Watches a specific variable and waits for a change in the variable's value. When there is a change, this method returns the new value or times out.


Creates a Waiter resource. This operation returns a long-running Operation resource which can be polled for completion. However, a waiter with the given name will exist (and can be retrieved) prior to the operation completing. If the operation fails, the failed Waiter resource will still exist and must be deleted prior to subsequent creation attempts.


Deletes the waiter with the specified name.


Gets information about a single waiter.


List waiters within the given configuration.


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.


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


A RuntimeConfig resource is the primary resource in the Cloud RuntimeConfig service. A RuntimeConfig resource consists of metadata and a hierarchy of variables.


Request message for SetIamPolicy method.


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:


Request message for TestIamPermissions method.


Response message for TestIamPermissions method.


Describes a single variable within a RuntimeConfig resource. The name denotes the hierarchical variable name. For example, ports/serving_port is a valid variable name. The variable value is an opaque string and only leaf variables can have values (that is, variables that do not have any child variables).


A Waiter resource waits for some end condition within a RuntimeConfig resource to be met before it returns. For example, assume you have a distributed system where each node writes to a Variable resource indicating the node's readiness as part of the startup process.


Request for the WatchVariable() method.



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



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



Type Definitions


A universal result type used as return for all calls.
