Saving into filesystem¶

We can implement a saving method that saves the deck to the filesystem.

def save(deck, filename) do
    binary = :erlang.term_to_binary(deck)
    File.write(filename, binary)
end

The :erlang invokes an erlang method called term_to_binary which basically converts the deck into an object that can be written onto a filesystem.

It saves it onto the filesystem in a binary mode.
