Issue #10344 has been updated by ioquatix (Samuel Williams).


I think this is a good idea. I already ended up implementing it by hand, but it's messy.

Feature #10344: [PATCH] Implement Fiber#raise
https://bugs.ruby-lang.org/issues/10344#change-75585

* Author: nome (Knut Franke)
* Status: Open
* Priority: Normal
* Assignee: ko1 (Koichi Sasada)
* Target version: 
----------------------------------------
While it is possible to implement this in pure Ruby (by wrapping Fiber.yield and Fiber#resume), this feels like a low-level feature that ought to be provided out of the box. Also, the C implementation is more straight-forward, and more efficient. Unfortunately, it is not quite possible to implement this as a C extension module (without resorting to wrappers again); cf. the change to make_passing_arg().

Example usage:

~~~
fib = Fiber.new do
  counter = 0
  loop { counter += Fiber.yield }
  counter
end
fib.resume
fib.resume 10
fib.resume 100
fib.raise StopIteration # => 110
~~~
