Module.split
You're seeing just the function
split, go back to Module module for more information.
Specs
Splits the given module name into binary parts.
module has to be an Elixir module, as split/1 won't work with Erlang-style
modules (for example, split(:lists) raises an error).
split/1 also supports splitting the string representation of Elixir modules
(that is, the result of calling Atom.to_string/1 with the module name).
Examples
iex> Module.split(Very.Long.Module.Name.And.Even.Longer)
["Very", "Long", "Module", "Name", "And", "Even", "Longer"]
iex> Module.split("Elixir.String.Chars")
["String", "Chars"]
