RPC server

To deploy the JsonRpcInterface, we'll need to create an RPC server using listen_and_serve(). listen_and_serve() is a method defined in DarkFi's rpc module. It starts a JSON-RPC server that is bound to the provided accept URL and uses our previously implemented RequestHandler to handle incoming requests.

Add the following lines to main():

{{#include ../../../../../example/dchat/src/main.rs:json_init}}

We create a new JsonRpcInterface inside an Arc pointer and pass in our accept_addr and p2p object.

Next, we create an async block that calls listen_and_serve(). The async block uses the move keyword to takes ownership of the accept_addr and JsonRpcInterface values and pass them into listen_and_serve(). We use an executor to spawn listen_and_serve() as a new thread and detach it in the background.

We have enabled JSON-RPC.

Here's what our complete main() function looks like:

{{#include ../../../../../example/dchat/src/main.rs:main}}
