This is not a language flamewar.
Each language has its focus area.
Rust wins on CPU bound operations while Elixir wins on IO bound ones.
I have been working on a small utility service in Elixir. It accepts a webhook to start. This spawns a process to do the work. The main work is a series of steps unified by a with block. The beauty is that it is all in small isolated files that you can see what it is doing. Having a repl in iex allows you to quickly experiment with services to see what is not working.
I am trying to read an equivalent Rust project to see how one of the system callx is used. Rust is high ceremony so there are many distinct declarations. The habbit of embedding the tests in the same files as the code makes searching for details far more painful than it needs to be.
