API docs for Rust servers

[arechsteiner]

Thank you for this reference implementation of a Rust RCON console.

Do you have any API documentation that describes the various commands that are available?

Also, is it possible to request some public information from a Rust server without the password (player count, and so on). Or how do services like battle metrics and rust monitor get all their info from servers they don't own?

Cheers and thank you
