Struct OperationsClient

pub struct OperationsClient<T> { /* private fields */ }

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][google.longrunning.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.

Implementations

impl OperationsClient<Channel>

pub async fn connect<D>(dst: D) -> Result<Self, Error>

where D: TryInto<Endpoint>, D::Error: Into<StdError>,

Attempt to create a new client by connecting to a given endpoint.

impl<T> OperationsClient<T>

where T: GrpcService<BoxBody>, T::Error: Into<StdError>, T::ResponseBody: Body<Data = Bytes> + Send + 'static, <T::ResponseBody as Body>::Error: Into<StdError> + Send,

pub fn new(inner: T) -> Self

pub fn with_origin(inner: T, origin: Uri) -> Self

pub fn with_interceptor<F>( inner: T, interceptor: F, ) -> OperationsClient<InterceptedService<T, F>>

where F: Interceptor, T::ResponseBody: Default, T: Service<Request<BoxBody>, Response = Response<<T as GrpcService<BoxBody>>::ResponseBody>>, <T as Service<Request<BoxBody>>>::Error: Into<StdError> + Send + Sync,

pub fn send_compressed(self, encoding: CompressionEncoding) -> Self

Compress requests with the given encoding.

This requires the server to support it otherwise it might respond with an error.

pub fn accept_compressed(self, encoding: CompressionEncoding) -> Self

Enable decompressing responses.

pub async fn list_operations( &mut self, request: impl IntoRequest<ListOperationsRequest>, ) -> Result<Response<ListOperationsResponse>, Status>

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

pub async fn get_operation( &mut self, request: impl IntoRequest<GetOperationRequest>, ) -> Result<Response<Operation>, Status>

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 async fn delete_operation( &mut self, request: impl IntoRequest<DeleteOperationRequest>, ) -> Result<Response<()>, Status>

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 async fn cancel_operation( &mut self, request: impl IntoRequest<CancelOperationRequest>, ) -> Result<Response<()>, Status>

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][google.longrunning.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][google.longrunning.Operation.error] value with a [google.rpc.Status.code][google.rpc.Status.code] of 1, corresponding to Code.CANCELLED.

pub async fn wait_operation( &mut self, request: impl IntoRequest<WaitOperationRequest>, ) -> Result<Response<Operation>, Status>

Waits until the specified long-running operation is done or reaches at most a specified timeout, returning the latest state. If the operation is already done, the latest state is immediately returned. If the timeout specified is greater than the default HTTP/RPC timeout, the HTTP/RPC timeout is used. If the server does not support this method, it returns google.rpc.Code.UNIMPLEMENTED. Note that this method is on a best-effort basis. It may return the latest state before the specified timeout (including immediately), meaning even an immediate response is no guarantee that the operation is done.

Trait Implementations
