Modern programming often requires us to guarantee how our applications terminate. One way to do this is through structured concurrency, which allows us to reason about parallel processes and how they relate. In this session, we will learn how to use Arrow’s Resource Domain-Specific Language (DSL) to reason about resource safety, like we use structured concurrency to avoid leaking resources. We will also see how this can be combined with KotlinX Coroutines to build complex use cases and elegantly use Kotlin DSLs. #kotlin #structuredconcurrency #coroutines Demo source code: https://github.com/nomisRev/ktor-k8s-...
