Available on crate feature client only.

JSON-RPC client interface that can make requests and notifications.

Required Methods

fn notification<Params>( &self, method: &str, params: Params, ) -> impl Future<Output = Result<(), Error>> + Send

where Params: ToRpcParams + Send,

Send a notification request

fn request<R, Params>( &self, method: &str, params: Params, ) -> impl Future<Output = Result<R, Error>> + Send

where R: DeserializeOwned, Params: ToRpcParams + Send,

Send a method call request.

fn batch_request<'a, R>( &self, batch: BatchRequestBuilder<'a>, ) -> impl Future<Output = Result<BatchResponse<'a, R>, Error>> + Send

where R: DeserializeOwned + Debug + 'a,

Send a batch request.

The response to batch are returned in the same order as it was inserted in the batch.

Returns Ok if all requests in the batch were answered. Returns Error if the network failed or any of the responses could be parsed a valid JSON-RPC response.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
