Accesing A Module's Structure

Tried that and got:
(CompileError) Cont.Expr.Inode.struct/1 is undefined, cannot expand struct Cont.Expr.Inode

Actually I think this might be a problem with the Atom/Elixir because I can compile and run this code

inode =  %Cont.Expr.Inode{value: 1234}

IO.inspect inode

And it ouputs

%Cont.Expr.Inode{value: 1234}

And Atom/Elixir displays this:

(CompileError) Cont.Expr.Inode.__struct__/1 is undefined, cannot expand struct Cont.Expr.Inode
