fuse-nio-adapter - FUSE-based adapter to provide directory contents specified by a java

•    Java

Access resources at a given NIO path via FUSE.

zio-nio - A small, unopinionated ZIO interface to NIO.

•    Scala

ZIO interface to Java NIO. Java NIO is unsafe, and can surprise you a lot with e.g. hiding the actual error in IO operation and giving you only true/false values when IO was successful/not successful. ZIO-NIO on the other hand embraces the full power of ZIO effects, environment, error and resource management to provide type-safe, performant, purely-functional, low-level, and unopinionated wrapping of Java NIO functionality.
