Transport implementation

Required Associated Types

type Out: Future<Output = Result<Value>>

The type of future this transport returns when a call is made.

Required Methods

fn prepare(&self, method: &str, params: Vec<Value>) -> (RequestId, Call)

Prepare serializable RPC call for given method with parameters.

fn send(&self, id: RequestId, request: Call) -> Self::Out

Execute prepared RPC call.

Provided Methods

fn execute(&self, method: &str, params: Vec<Value>) -> Self::Out

Execute remote method with given parameters.
