Struct AccessibilityPreferences 

pub struct AccessibilityPreferences {
    pub high_contrast: bool,
    pub reduced_motion: bool,
    pub text_scale_factor: f64,
}

Accessibility preferences read from the operating system.

Fields

high_contrast: bool

The user has enabled a high-contrast theme or mode.

reduced_motion: bool

The user has requested reduced or no animations.

text_scale_factor: f64

Text scaling factor (1.0 = normal, 1.25 = GNOME “Large Text”, up to 2.25 on Windows). On macOS this is always 1.0 — text scaling is handled via display DPI.

Implementations

impl AccessibilityPreferences

pub fn query() -> Self

Query current OS accessibility preferences.

This is a best-effort query. If a particular setting cannot be read (missing D-Bus service, unsupported desktop, etc.), the corresponding field falls back to its default value. Never panics.

pub fn prefers_large_text(&self) -> bool

Whether the user has requested larger text (text_scale_factor > 1.0).
