Problems with getting the server name
I only know that Server in Oxide.Game.Rust.Libraries.Server under the package,But I have no way of knowing which property or method gets the server name。How do I get the server name?

Also, is there any documentation like JAVA API documentation where you can easily check properties and methods?

If using a RustPlugin, it'd simply be Server.Name. For a CovalencePlugin, it'd be server.Name. There are native methods in Rust as well that these methods wrap, which you can find by decompiling the .dll files from the server.
