//! Sends asynchronous transactions.
//!
//! ## Example
//!
//! Constructs a signed transaction to be sent to an RPC node. It returns the transaction hash if successful.
//!
//! This code sample doesn't make any requests to the RPC node. It only shows how to construct the request. It's been truncated for brevity sake.
//!
//! A full example on how to use `broadcast_tx_async` method can be found at [`contract_change_method`](https://github.com/unc/unc-jsonrpc-client-rs/blob/master/examples/contract_change_method.rs).
//!
