Question

So Pants is made up with a network of rules Those rules are run when we call `Get Result Request data ` Pants assumes that `data` is immutable and forces `data` to be hashable This then allows Pants to memoise cache calls to `Get` so no matter how many times `Get Result Request 1 ` is called the rule will only ever get executed once Oh and everything is async How does Pants handle `MultiGet Get Result Request 1 Get Result Request 1 ` Is this undefined behaviour or can we still trust that the rule will only be ran once
