A data structure that typically models form validations, and other scenarios where
you want to aggregate all failures, rather than short-circuit if an error
happens (for which
Result is better suited).
Provides tools to model data structures in a functional way. The
union module allows simple definitions of tagged unions to model one-of-many possibilities.
