@ -241,11 +241,11 @@ it. This module lets you serialize and deserialize its own type easily.
For example:
```elixir
iex(1)> {serialized, ""} = %User{username: "stinky" id: 1234, first_name: "Stinky", last_name: "Stinkman"}
iex(1)> serialized = %User{username: "stinky" id: 1234, first_name: "Stinky", last_name: "Stinkman"}
|> User.BinaryProtocol.serialize
|> IO.iodata_to_binary
iex(2)> User.BinaryProtocol.deserialize(serialized)
{:ok, %User{username: "stinky" id: 1234, first_name: "Stinky", last_name: "Stinkman"}}
{%User{username: "stinky" id: 1234, first_name: "Stinky", last_name: "Stinkman"}, ""}
```
The return value of the `serialize` function is an [iodata]. You can pass it through `IO.iodata_to_binary` to convert it to a binary. You also can write the iodata directly to a file or socket without converting it.
