Struct SystemStyle 

#[repr(C)]
pub struct SystemStyle {
    pub theme: Theme,
    pub platform: Platform,
    pub colors: SystemColors,
    pub fonts: SystemFonts,
    pub metrics: SystemMetrics,
    pub language: AzString,
    pub app_specific_stylesheet: Option<Box<Stylesheet>>,
    pub icon_style: IconStyleOptions,
    pub scrollbar: Option<Box<ComputedScrollbarStyle>>,
}

A unified collection of discovered system style properties.

Fields

theme: Theme

platform: Platform

colors: SystemColors

fonts: SystemFonts

metrics: SystemMetrics

language: AzString

System language/locale in BCP 47 format (e.g., “en-US”, “de-DE”) Detected from OS settings at startup

app_specific_stylesheet: Option<Box<Stylesheet>>

An optional, user-provided stylesheet loaded from a conventional location (~/.config/azul/styles/<app_name>.css), allowing for application-specific “ricing”. This is only loaded when the “io” feature is enabled and not disabled by the AZUL_DISABLE_RICING env var.

icon_style: IconStyleOptions

Icon-specific styling options (grayscale, tinting, etc.)

scrollbar: Option<Box<ComputedScrollbarStyle>>

Scrollbar style information (boxed to ensure stable FFI size)

Implementations

impl SystemStyle

pub fn new() -> Self

Discovers the system’s UI style, and loads an optional app-specific stylesheet.

If the “io” feature is enabled, this function may be slow as it can involve running external commands and reading files.

If the “io” feature is disabled, this returns a hard-coded, deterministic style based on the target operating system.

pub fn create_csd_stylesheet(&self) -> Stylesheet

Create a CSS stylesheet for CSD (Client-Side Decorations) titlebar

This generates CSS rules for the CSD titlebar using system colors, fonts, and metrics to match the native platform look.

Trait Implementations

impl Clone for SystemStyle

fn clone(&self) -> SystemStyle

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SystemStyle

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

Formats the value using the given formatter.

impl Default for SystemStyle

fn default() -> SystemStyle

Returns the “default value” for a type.

impl PartialEq for SystemStyle

fn eq(&self, other: &SystemStyle) -> 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.
