coroutine size

[cheng dong]

thanks to runtime.newcoro/coroswitch and now we could do more things with coroutine. but it seems every newcoro create a full g which is 448B in size. maybe it is too heavy for a coroutine both in size and in schedule granularity ?

[cheng dong]

maybe coroutine could be implented inside a g in future hopefully

sorry, i found that 500k stack size might be nesessary for a coroutine, so its not a problem.

ahh, i really want to say is, can golang offer user a stateless coroutine.

I don’t think that is possible. You can have stackless coroutines, but if a coroutine has no state at all it would simply be implements as a method call chain without parameters in an executor. I doubt these are very useful.

stackless coroutine could not be replace by a method call chain, it might have loop and branch etc.
