Closes the port. Sending to a closed port is prohibited. Receiving is also prohibited if there are no messages in its message queue.

Only the Ractor which created the port is allowed to close it.

Example

port = Ractor::Port.new
Ractor.new port do |port|
  port.close #=> closing port by other ractors is not allowed (Ractor::Error)
end.join
