Errors and Promises

Packet Functions use Promises to handle asynchronous results and errors.

Successful Requests

Network.Server.RequestData:Invoke(nil, data):andThen(function(result)
  print(result)
end)

Failed Requests

If the callback throws an error, the Promise is rejected.

Example:

Network.Server.RequestData:Invoke(nil, data):catch(function(err)
  warn(err)
end)

Server:

Network.Server.RequestData:SetCallback(function()
  error("Something went wrong!")
end)

The error is automatically forwarded back to the caller.

Cancelling Requests

Promises can be cancelled:

local request = Network.Server.RequestData:Invoke(nil, data)

request:cancel()
