Description of Changes
Adds a validator for the coming fast-path BSATN -> BFLATN logic.
The validator is structured like the
row_type_visitor
, first converting to a rose tree and then to a byte code program.The goal with this is to, in most cases, have an empty validator program that is cheaper than tree traversal.
API and ABI breaking changes
None
Testing
A proptest is added asserting that the general PV -> BFLATN errors when the validator errors.
