Issue

The docs for PrimaryCommandBufferAbstract::execute, as well as PrimaryCommandBufferAbstract::execute_after read:

The command buffer is not actually executed until you call flush() on the object. You are encouraged to chain together as many futures as possible before calling flush(), and call .then_signal_future() before doing so. Note however that once you called execute() there is no way to cancel the execution, even if you didn’t flush yet.

There doesn't seem to be any method then_signal_future; this is probably meant to refer to one or all of the then_signal_fence(_*) or then_signal_semaphore(_*) methods.

(There's also some grammatical errors towards the end of the paragraph; I've sent #2128 for those. However, I'm not sure how the bits around "then_signal_future are supposed to read, so I didn't fix those, and hence, put that in this issue.)

Yeah that looks like a mistake, it should be then_signal_fence. Can you fix it as part of your PR?
