Consider connecting once and keeping the connection

[Kixunil]

Instead of connecting to the socket for every request connect only when the socket is created and use the same connection for subsequent requests. Admittedly, I don't know if this is supported by C-lightning, but I'd be highly surprised if not.

If retrying is desired, it might be handled by the client. There are already crates helping with this.

This might be related to #4.

The python binding also reconnects for every request, so I'm not sure that this is possible.

Also it would inherently serialize requests.

[Kixunil]

Would serializing requests be a problem?

[laanwj]

Maybe? It could be useful to be able to have multiple requests in progress at once, especially if there would be an async API. Some commands (waitinvoice etc) can wait pretty much forever.

[Kixunil]

That's a good point. It'd either had to be multiplexed somehow (if that's even possible) or handled from the outside. Alternatively, we could provide both APIs - the current one would be just a wrapper handling creating connection and calling appropriate request.

A quick experiment (no error handling or reconnection whatsoever) shows that c-lightning can handle multiple successive requests over a connection, at least: https://github.com/laanwj/rust-clightning-rpc/tree/experiment
