Method: Fiber#kill

Defined in:
cont.c

#kill ⇒ nil

Terminates the fiber by raising an uncatchable exception. It only terminates the given fiber and no other fiber, returning nil to another fiber if that fiber was calling #resume or #transfer.

Fiber#kill only interrupts another fiber when it is in Fiber.yield. If called on the current fiber then it raises that exception at the Fiber#kill call site.

If the fiber has not been started, transition directly to the terminated state.

If the fiber is already terminated, does nothing.

Raises FiberError if called on a fiber belonging to another thread.

Returns:

  • (nil)
