pub struct RpcChadClient {
req_send: Sender<JsonRequest>,
rep_recv: Receiver<JsonResult>,
task: StoppableTaskPtr,
}
Expand description
Highly experimental JSON-RPC client implementation using asynchronous channels, with each new request canceling waiting for the previous one. All requests are executed without a timeout.
Fields§
§req_send: Sender<JsonRequest>
The channel used to send JSON-RPC request objects
rep_recv: Receiver<JsonResult>
The channel used to read the JSON-RPC response object
task: StoppableTaskPtr
The stoppable task pointer, used on RpcChadClient::stop()
Implementations§
Source§impl RpcChadClient
impl RpcChadClient
Sourcepub async fn new(endpoint: Url, ex: Arc<Executor<'_>>) -> Result<Self>
pub async fn new(endpoint: Url, ex: Arc<Executor<'_>>) -> Result<Self>
Instantiate a new JSON-RPC client that connects to the given endpoint.
The function takes an Executor
object, which is needed to start the
StoppableTask
which represents the client-server connection.
Sourcepub async fn stop(&self)
pub async fn stop(&self)
Stop the JSON-RPC client. This will trigger stop()
on the inner
StoppableTaskPtr
resulting in stopping the internal reqrep loop
and therefore closing the connection.
Sourceasync fn reqrep_loop(
use_http: bool,
stream: Box<dyn PtStream>,
rep_send: Sender<JsonResult>,
req_recv: Receiver<JsonRequest>,
) -> Result<()>
async fn reqrep_loop( use_http: bool, stream: Box<dyn PtStream>, rep_send: Sender<JsonResult>, req_recv: Receiver<JsonRequest>, ) -> Result<()>
Internal function that loops on a given stream and multiplexes the data
Sourcepub async fn request(&self, req: JsonRequest) -> Result<JsonValue>
pub async fn request(&self, req: JsonRequest) -> Result<JsonValue>
Send a given JSON-RPC request over the instantiated client and
return a possible result. If the response is an error, returns
a JsonRpcError
.
