+> Handcrafted, artisanal Scala Native bindings for libuv.

 **scala-uv** is a Scala Native library that provides Scala bindings for [libuv](https://libuv.org), which is a multi-platform asynchronous IO library written in C. libuv was originally developed for Node.js, but it's also used by other software projects.

+Very early days, most of the APIs have bindings, but not all. Many are not tested at all. What I've tried so far:
 
 * Error handling
 * Event loop
 * Async callbacks
 * Read and write files

 While the `Zone` memory allocation API from Scala Native is very nice, it's not useful when the memory is freed in a different callback, as there won't be a shared lexical scope. So `mallocCString` converts a Scala string to a C string, allocating the memory the old-fashioned way.
