# Nif for Elixir.ExOpenssl.Nif

## To build the NIF module:

  * Make sure your projects `mix.exs` has the `:rustler` compiler listed in the `project` function: `compilers: [:rustler] ++ Mix.compilers` If there already is a `:compilers` list, you should append `:rustler` to it.
  * Add your crate to the `rustler_crates` attribute in the `project function. [See here](https://hexdocs.pm/rustler/basics.html#crate-configuration).
  * Your NIF will now build along with your project.

## To load the NIF:

```elixir
defmodule ExOpenssl.Nif do
    use Rustler, otp_app: [otp app], crate: "exopenssl"

    # When your NIF is loaded, it will override this function.
    def add(_a, _b), do: throw :nif_not_loaded
end
```
