Struct XScalingMode

pub struct XScalingMode(pub u32);

The scaling mode of X windows.

Tuple Fields

0: u32

Implementations

impl XScalingMode

pub const DEFAULT: Self

The default mode.

Currently this means that windows are rendered at the lowest scale and then upscaled if necessary.

pub const DOWNSCALED: Self

Windows are rendered at the highest integer scale and then downscaled.

This has significant performance implications unless the window is running on the output with the highest scale and that scale is an integer scale.

For example, on a 3840x2160 output with a 1.5 scale, a fullscreen window will be rendered at 3840x2160 * 2 / 1.5 = 5120x2880 pixels and then downscaled to 3840x2160. This overhead gets worse the lower the scale of the output is.

Additionally, this mode requires the X window to scale its contents itself. In the example above, you might achieve this by setting the environment variable GDK_SCALE=2.

Trait Implementations

impl Clone for XScalingMode

fn clone(&self) -> XScalingMode

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for XScalingMode

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

Formats the value using the given formatter.

impl Default for XScalingMode

fn default() -> XScalingMode

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for XScalingMode

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Hash for XScalingMode

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for XScalingMode

fn eq(&self, other: &XScalingMode) -> 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 Serialize for XScalingMode

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
