Struct QrOptions 

pub struct QrOptions {
    pub scale: u32,
    pub border: usize,
    pub dark_color: Rgb<u8>,
    pub light_color: Rgb<u8>,
}

border: usize

Quiet zone border size in modules (default: 4)

dark_color: Rgb<u8>

RGB color for dark modules

light_color: Rgb<u8>

RGB color for light modules (background)
