pub type PupEntry = fn(Packed, Packed, Vec<Packed>) -> Result<Packed, PackedError>;Expand description
The signature of the generated trampoline a pup runs: build a fresh world from
the globals snapshot, unpack the callee and its arguments, run the call, and
pack the result (or the error) for the trip home. A plain fn pointer, so it
is Send and can be handed to a spawned thread.
