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 ~~~ ---Files-------------------------------- 0001-Implement-Fiber-raise.patch (4.12 KB) -- https://bugs.ruby-lang.org/
