Struct HeadlessMonitor 

#[non_exhaustive]
pub struct HeadlessMonitor {
    pub scale_factor: Option<Factor>,
    pub size: DipSize,
    pub density: PxDensity,
}

“Monitor” configuration used by windows in headless mode.

Fields (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: DipSize

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.

Implementations

impl HeadlessMonitor

pub fn new(size: DipSize) -> Self

New with custom size at None scale.

pub fn new_scaled(size: DipSize, scale_factor: Factor) -> Self

New with custom size and scale.

pub fn new_scale(scale_factor: Factor) -> Self

New with default size (11608, 8708) and custom scale.

Trait Implementations

impl Clone for HeadlessMonitor

fn clone(&self) -> HeadlessMonitor

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for HeadlessMonitor

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for HeadlessMonitor

fn default() -> Self

New (11608, 8708) at None scale.

impl<W: Into<Dip>, H: Into<Dip>> From<(W, H)> for HeadlessMonitor

fn from((width, height): (W, H)) -> Self

Converts to this type from the input type.

impl<W: Into<Dip>, H: Into<Dip>, F: Into<Factor>> From<(W, H, F)> for HeadlessMonitor

fn from((width, height, scale): (W, H, F)) -> Self

Converts to this type from the input type.

impl<W: Into<Dip>, H: Into<Dip>> IntoVar<HeadlessMonitor> for (W, H)

fn into_var(self) -> Var<HeadlessMonitor>

impl<W: Into<Dip>, H: Into<Dip>, F: Into<Factor>> IntoVar<HeadlessMonitor> for (W, H, F)

fn into_var(self) -> Var<HeadlessMonitor>

impl PartialEq for HeadlessMonitor

fn eq(&self, other: &HeadlessMonitor) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Copy for HeadlessMonitor
