(Elixir/Erlang) How to get the source code file line total numbers from an Erlang beam file?

Is this information contained in these chunks of the Beam file? Or is there another way?

For a beam file compiled from Erlang, you can get the number of lines like this:

{ok,{_ModuleName,[{debug_info,{debug_info_v1,erl_abstract_code, DebugInfoData}}]}} =
   beam_lib:chunks("my_module", [debug_info]).
{ok, Defs} = erl_abstract_code:debug_info(erlang_v1, x, DebugInfoData, []).
{eof, {Lines, _}} = lists:last(Defs).

Replace "my_module" with the file name of the beam file without the .beam extension.
