erl_interface.rs

================

Attempt at a rust wrapper for `erl_interface `_ C API.

Disclaimer: I have yet to learn rust, this is me writing C in rust syntax until it compiles.

Build

-----

::

    cargo build

Run

---

Change hostname for your hostname (appears on the erlang shell)

::

    erl -sname e1 -setcookie secretcookie

    cargo run e1@hostname secretcookie

In the erlang sell send something::

    (e1@hostname)1> {any, c1@hostname} ! self().

On the rust side you should see something like::

    got a send! Pid(e1@hostname, 39, 0, 1)

If you send something like {pid(), any()} it will send you back any(), let's try it.

Start the erlang node as explained above::

    erl -sname e1 -setcookie secretcookie

Then start the rust node::

    cargo run e1@hostname secretcookie

         Running `target/debug/erl_interface e1@hostname secretcookie`

    Connected to e1@hostname

From the erlang shell send the message with the format explained above::

    (e1@hostname)33> {any, c1@hostname} ! {self(), [32, 1.4, foo, {<<"asd">>, "lala"}]}.

    {<0.39.0>,[32,1.4,foo,{<<"asd">>,"lala"}]}

On the rust node you should see::

    got echo! sending List(size: 4, items: (Int(32), Float(1.4), Atom(foo), Tuple(size: 2, items: (Binary(size: 3, items: (97, 115, 100)), List(size: 4, items: (Int(108), Int(97), Int(108), Int(97)))))))

And flushing received messages on the erlang node you should see::

    (e1@hostname)34> flush().

    Shell got [32,1.4,foo,{<<"asd">>,"lala"}]

    ok
