is there an easy way to access the generated schema from prisma? I have found

*ScalarFieldEnum

but I'm thinking it might be an easier way to get it programmatically? My use case is that in a middleware I want to rewrite a where statement to search in another field if it exists.

prisma.model.findFirst({ where: firstName: 'max' })

but I want to rewrite that to

prisma.model.findFirst({ where: firstName_hash: 'HASH OF FIRSTNAME' })

iff the

firstName_hash

field exists?
