Add function for ping command about mongo-rust-driver HOT 2 CLOSED

Hello, just found myself going back to this feature request.

Right now it's easy to construct a client with a connection string that would never successfully connect. And without some form of health check, you would not find out until you send a command of sorts and it times out. Which would cause user requests to be timed out.

Probing whether we can connect and there's a mongodb server on the other end of the line ready to take requests, seems exactly what ping is meant for. So the relying service most likely will want to confirm this before marking itself as healthy and ready to serve requests.

A bit confused why API stability is the reason not to implement this. Since the ping command doesn't appear to have changed on the server since 4.4.

That said, @ISibboI's workaround of using run_command instead works too. 😄

Hi!

We appreciate the suggestion - however, we have to carefully weigh what functionality we build into the API because we place a high priority on API stability. In this case, because the added utility is very minor it's unlikely to be something we'll want to turn into an API commitment.
