Struct Operations

pub struct Operations { /* private fields */ }

Implements a client for the Long Running Operations API.

Example

let client = Operations::builder().build().await?;
// use `client` to make requests to the Long Running Operations API.

Service Description

Manages long-running operations with an API service.

When an API method normally takes long time to complete, it can be designed to return Operation to the client, and the client can use this interface to receive the real response asynchronously by polling the operation resource, or pass the operation resource to another API (such as Pub/Sub API) to receive the response. Any API service that returns long-running operations should implement the Operations interface so developers can have a consistent client experience.

Configuration

To configure Operations use the with_* methods in the type returned by builder(). The default configuration should work for most applications. Common configuration changes include

• with_endpoint(): by default this client uses the global default endpoint (https://longrunning.googleapis.com). Applications using regional endpoints or running in restricted networks (e.g. a network configured override this default.
• with_credentials(): by default this client uses Application Default Credentials. Applications using custom authentication may need to override this default.

Pooling and Cloning

Operations holds a connection pool internally, it is advised to create one and the reuse it. You do not need to wrap Operations in an Rc or Arc to reuse it, because it already uses an Arc internally.

Implementations

impl Operations

pub fn builder() -> ClientBuilder

Returns a builder for Operations.

let client = Operations::builder().build().await?;

pub fn from_stub<T>(stub: T) -> Self

where T: Operations + 'static,

Creates a new client from the provided stub.

The most common case for calling this function is in tests mocking the client’s behavior.

pub fn list_operations(&self) -> ListOperations

Lists operations that match the specified filter in the request. If the server doesn’t support this method, it returns UNIMPLEMENTED.

pub fn get_operation(&self) -> GetOperation

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.

pub fn delete_operation(&self) -> DeleteOperation

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.

pub fn cancel_operation(&self) -> CancelOperation

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 to Code.CANCELLED.

Trait Implementations

impl Clone for Operations

fn clone(&self) -> Operations

Returns a duplicate of the value.

const fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Operations

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
