Two important things should be changed in the Rust docs

[xNul]

First, the command to send a message located here does not work correctly (at least on Windows). With single quotes, the text sent to the database is 'Hello,. In order to send the whole Hello, World! message, you have to use double quotes. The whole command should be spacetime call <module-name> send_message "Hello, World!".

Second, using spacetime start is never mentioned as a prerequisite. If you follow the guide without doing that, you get this error message:

>spacetime publish --project-path server quickstart-chat-module

Caused by:

    2: No connection could be made because the target machine actively refused it. (os error 10061)

which is unclear as well. It would be good to have a check before the spacetime CLI tries to connect to the database to determine if it is up in the first place.
