Fast, Simple Concurrency with Scala Native

Explore fast and simple concurrency with Scala Native in this conference talk from Scala Days Lausanne 2019. Dive into the background of concurrency, common issues, and design questions before introducing libUV and its integration with Scala Native. Learn about native-loop, streams implementation, and server APIs. Examine performance considerations and systems programming concepts, including memory allocation and C FFI. Discover how to build an ExecutionContext from scratch using libUV's event loop. Gain insights into working with opaque structs and explore future developments in Scala Native concurrency.
