Hi all. How would one model a fan-in within a composite solid? Unlike in the fan-in-fan-out example, it seems like you can’t return a single output that is a collection of
SolidOutputHandle
’s from a composite solid, but you can make an identity
lambda_solid
and return the output of that.

ya we only model “fan-in” on inputs currently, so you have correctly identified the limitation and probably best workaround. Your other option would be to have the composite map all its outputs and then collect them and fan them in where you use it.
if you have the time, please file an issue with some context on your use case. I can guess how it could be useful, but we really appreciate concrete user examples when we can get them.
