Rich Errors in Kotlin
Kotlin's nullability model is one of its core features. In this talk, we’ll explore how this model can be generalized to restricted union types specifically designed for handling error cases.
Additionally, we’ll discuss how errors can currently be represented in Kotlin, covering approaches such as nullable types, exceptions, sealed hierarchies, and Result-like classes.
