Overview

The basic client class that is used to connect to Discord, send REST requests, or send or receive gateway messages. It is required for doing any sort of interaction with Discord.

A new simple client that does nothing yet can be created like this:

client = Discord::Client.new(token: "Bot token", client_id: 123_u64)

With this client, REST requests can now be sent. (See the Discord::REST module.) A gateway connection can also be started using the #run method.
