Anyway please update NEWS now to avoid forgetting adding the description. ---------------------------------------- Feature #10344: [PATCH] Implement Fiber#raise https://bugs.ruby-lang.org/issues/10344#change-76017 * Author: nome (Knut Franke) * Status: Closed * Priority: Normal * Assignee: ioquatix (Samuel Williams) * Target version: 2.7 ---------------------------------------- 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 ~~~ ---Files-------------------------------- 0001-Implement-Fiber-raise.patch (4.12 KB) 0001-Implement-Fiber-raise.patch (3.51 KB) 0001-Implement-Fiber-raise-in-ext-fiber.patch (3.6 KB) -- https://bugs.ruby-lang.org/ Unsubscribe:
