Goal

Scalaz NIO provides performant, purely-functional, low-level, and unopinionated wrapping of Java NIO functionality.

Introduction & Highlights

Java NIO is unsafe, and can surprise you a lot with e.g. hiding actual error in IO operation and giving you only true/false values - IO was seccessful/not successful.
