co-log: Composable Contravariant Comonadic Logging Component
YOW! Lambda Jam 2019
In this talk I'm going to share key design decisions behind Haskell logging library called co-log.
This library combines multiple algebraic concepts in order to provide convenient and composable solution for the logging problem:
- Semigroup and Monoid
I'm also going to show how we use this library in commercial Haskell projects.
