What is FS2?
FS2 is a library for purely functional, effectful, and polymorphic stream processing in the Scala programming language. Its design goals are compositionality, expressiveness, resource safety, and speed. FS2 is built upon Cats and Cats-Effect, and its core types (streams and pulls) are polymorphic in the effect type, allowing it to be used with other effect libraries.
