Defined in: | ractor.c, ractor.c |
Overview
Raised when an attempt is made to send a message to a closed port, or to retrieve a message from a closed and empty port. Ports may be closed explicitly with Ractor#close_outgoing/close_incoming
and are closed implicitly when a ::Ractor
terminates.
r = Ractor.new { sleep(500) }
r.close_outgoing
r.take # Ractor::ClosedError
ClosedError
is a descendant of ::StopIteration
, so the closing of the ractor will break the loops without propagating the error:
r = Ractor.new do
loop do
msg = receive # raises ClosedError and loop traps it
puts "Received: #{msg}"
end
puts "loop exited"
end
3.times{|i| r << i}
r.close_incoming
r.take
puts "Continue successfully"
This will print:
Received: 0
Received: 1
Received: 2
loop exited
Continue successfully
