Rustler is a library for writing Erlang NIFs in safe Rust code
I've been trying to decide between learning Elixir and learning Rust and Elixir had a narrow lead because of employment potential and my growing dissatisfaction with Docker (container orchestration contains an ad-hoc, informally-specified, bug-ridden, slow implementation of half of Erlang).Then I learned that the Achilles' heel of the BEAM VM is that if native code crashes it takes the whole thing with it, so people have been using Rust for native code (NIFs).  So now the plan is Elixir then Rust which is easing my FOMO quite a bit.
