Struct HeadlessMonitor 

Source 
#[non_exhaustive]
pub struct HeadlessMonitor {
    pub scale_factor: Option<Factor>,
    pub size: Size2D<Dip, Dip>,
    pub density: PxDensity,
}
Expand description

“Monitor” configuration used by windows in headless mode.

Fields (Non-exhaustive)§

This struct is marked as non-exhaustive
Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.
§scale_factor: Option<Factor>

The scale factor used for the headless layout and rendering.

If set to None, falls back to the parent scale-factor, or 1.0 if the headless window has not parent.

None by default.

§size: Size2D<Dip, Dip>

Size of the imaginary monitor screen that contains the headless window.

This is used to calculate relative lengths in the window size definition and is defined in layout pixels instead of device like in a real monitor info.

(11608, 8708) by default.

§density: PxDensity

Pixel density used for the headless layout and rendering.
