no string in pallets, the current implementation make it hard for sdk users to figure out the meaning of this
it could be an enum
but I don’t think the current event make sense as there are only 3 possibilities: main success, mail failed + fallback success, all failed
the all failed case should just result the whole call to be failed. ie no extra event. so we only really two event: main success, and fallback called
|
looks fine now. need proper weights |
|
I am guessing the weight signature below the pallet index will have some form of condition as well? |
|
use the worst case (i.e. main + fallback). extra weight will be refunded as the actual weight is returned in the call |
this also applies to dispatch class? |
I would say dispatch class is the lowest class of the 2. if both are operational then it is operational. if one is normal then it is normal. etc. |
how can one determine the class of a |

The err branch should be slightly more costly, but difference should be negligible so it is ok.

Ok.

Maybe 2 more tests:
- successful main call.
- failing else call.

Need the CI to run some checks @ggwpez 🙏 |
