Simple utility library that performs native extended attribute operations using rustler and the xattr crate created by Steven Allen.

In theory this should support every platform the xattr crate supports, which includes: Android, Linux, MacOS, FreeBSD, and NetBSD. However I've only tested this on Linux.

I was disappointed to see that there was no native interface within Elixir or Erlang's standard libraries for managing extended attributes. While this can technically be worked around by simply wrapping the setfattr and getfattr commands, I wasn't happy with the performance of this approach.

Additionally, while there are similar libraries that handle xattr operations for Elixir, I'm picky about how I handle serialization and was looking for something less opinionated and "dumb" that I could easily wrap my application specific logic around.

Since I couldn't find anything that fit this criteria I figured I'd just do it myself, and so here we are!

The package can be installed by adding ex_attr to your list of dependencies in mix.exs:

def deps do
  [
    {:ex_attr, "~> 2.0.0"}
  ]
end
