Method: Fiber#storage=

Defined in:

cont.c

#storage=(hash) ⇒ Object

Sets the storage hash for the fiber. This feature is experimental and may change in the future. The method can only be called on the Fiber.current.

You should be careful about using this method as you may inadvertently clear important fiber-storage state. You should mostly prefer to assign specific keys in the storage using Fiber::[]=.

You can also use Fiber.new(storage: nil) to create a fiber with an empty storage.

Example:

while request = request_queue.pop
  # Reset the per-request state:
  Fiber.current.storage = nil
  handle_request(request)
end

# File 'cont.c', line 2099
