Peeking Inside the Engine of ZIO SQL by Jaroslav Regec

"Peeking Inside the Engine of ZIO SQL" by Jaroslav Regec at Functional Scala 2022.

One of the biggest challenges that library authors face, is to preserve type-safety while eliminating boilerplate that the users have to deal with.

In this talk, Jaro takes a look at a few tricks that ZIO SQL uses - ZIO Schema's reified optics, Implicits, and Macros - which allows the library to offer 100% type-safe DSL while keeping boilerplate to a minimum.
