Struct re_protos::sdk_comms::v0::message_proxy_client::MessageProxyClient

pub struct MessageProxyClient<T> {
    inner: Grpc<T>,
}

Simple buffer for messages between SDKs and viewers.

• SDKs produce messages by calling WriteMessages
• Viewers consume messages by calling ReadMessages

The buffer is bounded by a memory limit, and will drop the oldest messages when the limit is reached.

Whenever ReadMessages is called, all buffered messages are sent in the order they were received. The stream will then also yield any new messages passed to WriteMessages from any client.

Fields

inner: Grpc<T>

Implementations

impl<T> MessageProxyClient<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, ) -> MessageProxyClient<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 fn max_decoding_message_size(self, limit: usize) -> Self

Limits the maximum size of a decoded message.

Default: 4MB

pub fn max_encoding_message_size(self, limit: usize) -> Self

Limits the maximum size of an encoded message.

Default: usize::MAX

pub async fn write_messages( &mut self, request: impl IntoStreamingRequest<Message = LogMsg>, ) -> Result<Response<Empty>, Status>

TODO(jan): Would it be more efficient to send a “message batch” instead of individual messages? It may allow us to amortize the overhead of the gRPC protocol.

pub async fn read_messages( &mut self, request: impl IntoRequest<Empty>, ) -> Result<Response<Streaming<LogMsg>>, Status>

Trait Implementations

fn clone(&self) -> MessageProxyClient<T>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<T: Debug> Debug for MessageProxyClient<T>

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