Motivation
Closes #392
Fix here prevents zero-sized types from adding significant overhead to decoding, this is an alternative to the proposed fix of disabling instantiation of ZSTs.
DynSolType
has many instantiation vectors, and we may not be able to effectively prevent incorrect use of all of them.Followup: research whether we can do this effectively
Solution
Add an
is_zst
check to decoding, which short-circuits decoding of zero-sized values.PR Checklist
