Trait tuig_ui::attachments::Attachment

pub trait Attachment<'s> {
    type Output;

    // Required method
    fn attach(self, region: Region<'s>) -> Self::Output;
}

Something that can be put into a Region.

Deciding when to implement Attachment – versus just fiddling with regions in the parent attachment – can be difficult, like most software design problems. It’s a balancing act between the extra boilerplate and the extra segmentation. Follow the single-responsibility principle, keep your code DRY, etc.

Implementing this trait directly will let you fiddle with Regions and, generally, is the high-level interface. If you need the lower-level interface to actually handle input and draw to the character grid, you’ll need to impl RawAttachment, or make use of FnOnce(Action, ScreenView) implementing RawAttachment.
