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
