Elixir and Rust - learning Rust a necessary skill for people using Elixir?

Nah, the thing with Rust is that it’s a nice language and people are able to implement NIFs with it thanks to Rustler. And you need NIFs when you have already exhausted all the tools available in elixir/erlang or need to squeeze every bit of performance for a specific operation by working outside of the beam.

So don’t worry about it.

Writing NIFs is something that most Elixir developers won’t ever want/need to do. Unless you have some particular use case in mind which will require the use of NIFs, I don’t think you need worry. Cross that bridge when you come to it.

Thank you very much for the detailed answer.
But I didn’t understand why then the community is so
celebrating the appearance of the Rustler library?

Because it makes it easy to interface rust, and takes the burden of a lot of boilerplate code you had to write otherwise to interface with the erlang distributed C-Headers for writing NIFs.

And Rust is memory safe and fast, C is just fast. Thats why Rust is so much prefered over C, though its possible to write NIFs in C or C++ as well, or even Pascal or anything else that is able to call into C and gets called from C. But not everything makes sense…

Erlang and Elixir are excellent glue languages, and excellent in handling a lot of network requests at once. You’ll be very hard-pressed to find another runtime that does these things so rock-solid and fast.

That being said, they definitely fall short if you need mega-fast processing that requires pure CPU muscle – like various matrix calculations, deep learning, image processing, those kinds of things.

People praise Rustler because, as @NobbZ said, it makes it very easy to integrate your own Rust code with your Elixir code. But that’s only if you need it. Most of the BEAM projects are perfectly fine being Erlang or Elixir only.

Thank you all very much.
But another question.

Could such a situation may be arise:

To learn the Scala, or clojure you need to know Java.
To learn the Elixir, you need to know Erlang and Rurt?

To learn elixir you only need to learn elixir.

Maybe later if you start doing some really, really cool stuff you might want to learn Erlang or Rust.

But at that point that’s a good problem to have … because you’re doing cool stuff

Thanks to all.

Thank You.
I have already started.
It was very pleasant to have a drink while
feeling support at such a distance.
