    // Required method
    fn send_batch<T>(&self, requests: T) -> Self::Batch
       where T: IntoIterator<Item = (RequestId, Call)>;
}

A transport implementation supporting batch requests.

Required Associated Types

type Batch: Future<Output = Result<Vec<Result<Value>>>>

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

Required Methods

fn send_batch<T>(&self, requests: T) -> Self::Batchwhere T: IntoIterator<Item = (RequestId, Call)>,

Sends a batch of prepared RPC calls.
