Die if uinput module is neither loaded nor built into the kernel #30
Conversation

Holy frijoles, Batman. In my testing, this works correctly, dies when it should, and announces accurately that uinput is either a loaded module or is built into the kernel. HOWEVER, I strongly suspect my completely ignorant coding style in Rust will look to those who know Rust ... like completely ignorant coding style in Rust. I do not ask you developers to "go easy on me; it's my first try at this," but rather to be brutal and instructive. I have a thick skin and would rather learn than be treated gently. It took me about seven hours of learning Rust notions to make something that would compile ... and another two to make something that would do what it was intended to do. This does not mean that what little I've written is stylistically desirable Rust. I come from Java (despite hating Java) and my only coding pal (we're both dentists, not professional developers, though he is a significantly better coder than am I) regularly notes that whether I write Haskell, Python or C, it all looks like Java. (EDIT: Also, I really thought I would have this done in twenty minutes when I sat down to do it. : ) |

Thanks for the PR
How confident are you about this being cross-platform? Will it work across most popular linux desktop distros/kernel versions?

I am confident only that it compiles cleanly on Arch. Your question is very fair. I have not tested it on other Linux distros/kernels.
