API::Discord::Connection - Combines a websocket and a REST client


Discord sends us information over the websocket, and we send it stuff over the
REST client. Mostly.


This is used internally and probably of limited use otherwise.


my $c = API::Discord::Connection.new:
    :url(wss://...),
    :$token,
;



#| Websocket URL
has Str $.ws-url is required;
#| REST URL
has Str $.rest-url is required;
#| User's bot/API token
has Str $.token is required;
#| See discord docs on intents
has Int $.intents is required;
#| Allows multiple instances to run the same bot
has Int $.shard = 0;
has Int $.shards-max = 1;

#| The Cro HTTP client used for REST-y stuff.
has Cro::HTTP::Client $!rest;

#| The Discord WebSocket object, which parses raw WebSocket messages into Discord
#| messages, as well as handling protocol details such as sessions, sequences, and
#| heartbeats. There may be many connections over the lifetime of this object.
has API::Discord::WebSocket $!websocket .= new(
    :$!ws-url,
    :$!token,
    :$!intents,
);

#| This Promise is kept when Discord has sent us a READY event
has Promise $.ready = Promise.new;



C<$.ws-url>, C<$.rest-url> and C<$.token> are required here.



submethod TWEAK {
    # TODO: We should also take the user-agent URL and the REST URL as
    # constructor parameters
    $!rest = Cro::HTTP::Client.new(
        content-type => 'application/json',
