Working on extending displayz to other platforms. #2

Hi,

I'm working on a Rust, cross-platform (Windows, macOS, Linux/BSD) profile-based display output manager. It's event-based but also can be controlled with JSON-RPC.

displayz looks perfect for Windows, but I found myself duplicating efforts in my usage of this crate.

I thought, maybe, it might be a good idea to work on creating a generic DisplayOutput trait for displayz, that, when combined with the target_os attribute, can provide platform-specific implementations of the display outputs.

To give you an idea of how I picture a DisplayOutput trait, here's some code I wrote, and then realized I was duplicating efforts, for automon:

pub type Resolution = (usize, usize);
pub type Position = (usize, usize);

pub trait DisplayOutput {
    pub fn is_primary(&self) -> bool;
    pub fn is_active(&self) -> bool;
    pub fn get_pos(&self) -> Position;
    pub fn get_res(&self) -> Resolution;
}

I'd really like to work on adding the modern API (but also maintaining backwards-compatibility, if possible) with you, and extending the scope of displayz to macOS, Linux, and BSD.

What do you think?

Have a great weekend! :)
