CommandCompletionServiceClient

canton_ledger::proto::command_completion_service_client

Struct CommandCompletionServiceClient 

Source 
pub struct CommandCompletionServiceClient<T> { /* private fields */ }
Expand description

Allows clients to observe the status of their submissions. Commands may be submitted via the Command Submission Service. The on-ledger effects of their submissions are disclosed by the Update Service.

Commands may fail in 2 distinct manners:

  1. Failure communicated synchronously in the gRPC error of the submission.
  2. Failure communicated asynchronously in a Completion, see completion.proto.

Note that not only successfully submitted commands MAY produce a completion event. For example, the participant MAY choose to produce a completion event for a rejection of a duplicate command.

Clients that do not receive a successful completion about their submission MUST NOT assume that it was successful. Clients SHOULD subscribe to the CompletionStream before starting to submit commands to prevent race conditions.

Implementations§

Source§

impl CommandCompletionServiceClient<Channel>

Source

pub async fn connect<D>( dst: D, ) -> Result<CommandCompletionServiceClient<Channel>, Error>
where D: TryInto<Endpoint>, <D as TryInto<Endpoint>>::Error: Into<Box<dyn Error + Sync + Send>>,

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

impl<T> CommandCompletionServiceClient<T>
where T: GrpcService<Body>, <T as GrpcService<Body>>::Error: Into<Box<dyn Error + Sync + Send>>, <T as GrpcService<Body>>::ResponseBody: Body<Data = Bytes> + Send + 'static, <<T as GrpcService<Body>>::ResponseBody as Body>::Error: Into<Box<dyn Error + Sync + Send>> + Send,

Source

pub fn new(inner: T) -> CommandCompletionServiceClient<T>

Source

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

Source

pub fn with_interceptor<F>( inner: T, interceptor: F, ) -> CommandCompletionServiceClient<InterceptedService<T, F>>
where F: Interceptor, <T as GrpcService<Body>>::ResponseBody: Default, T: Service<Request<Body>, Response = Response<<T as GrpcService<Body>>::ResponseBody>>, <T as Service<Request<Body>>>::Error: Into<Box<dyn Error + Sync + Send>> + Send + Sync,

Source

pub fn send_compressed( self, encoding: CompressionEncoding, ) -> CommandCompletionServiceClient<T>

Compress requests with the given encoding.

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

Source

pub fn accept_compressed( self, encoding: CompressionEncoding, ) -> CommandCompletionServiceClient<T>

Enable decompressing responses.

Source

pub fn max_decoding_message_size( self, limit: usize, ) -> CommandCompletionServiceClient<T>

Limits the maximum size of a decoded message.

Default: 4MB

Source

pub fn max_encoding_message_size( self, limit: usize, ) -> CommandCompletionServiceClient<T>

Limits the maximum size of an encoded message.

Default: usize::MAX

Source

pub async fn completion_stream( &mut self, request: impl IntoRequest<CompletionStreamRequest>, ) -> Result<Response<Streaming<CompletionStreamResponse>>, Status>

Deprecated: please use GetCompletions instead. Subscribe to command completion events.

Source

pub async fn get_completions( &mut self, request: impl IntoRequest<GetCompletionsRequest>, ) -> Result<Response<Streaming<CompletionStreamResponse>>, Status>

Subscribe to command completion events. This streaming endpoint provides more flexibility in filtering than the predecessor CompletionStream.
