Struct AccessibilityPreferences 

pub struct AccessibilityPreferences {
    pub reduce_motion: bool,
    pub reduce_transparency: bool,
    pub increase_contrast: bool,
}

System accessibility preferences that components and the renderer must honor.

These map to macOS System Settings > Accessibility:

• reduce_motion: Disables non-essential animations (spring, bounce, etc.)
• reduce_transparency: Replaces glass/transparent materials with opaque surfaces
• increase_contrast: Makes all borders visible, minimum alpha 0.5 for all elements

Fields

reduce_motion: bool

User prefers reduced motion. Animations should be instant or very short.

reduce_transparency: bool

User prefers reduced transparency. Glass materials should be opaque.

increase_contrast: bool

User prefers increased contrast. Borders must be visible, min alpha 0.5.

Implementations

impl AccessibilityPreferences

pub fn detect_from_system() -> Self

Detect system accessibility preferences (macOS).

On non-macOS platforms, returns defaults (all false). In a production implementation, this would query the OS APIs.

pub fn min_alpha(&self, requested: f32) -> f32

Apply a minimum alpha constraint for increase-contrast mode.

pub fn should_disable_glass(&self) -> bool

Returns true if glass effects should be replaced with opaque surfaces.

pub fn should_reduce_motion(&self) -> bool

Returns true if animations should be instant.

pub fn should_increase_contrast(&self) -> bool

Returns true if borders should be made visible.

Trait Implementations

impl Clone for AccessibilityPreferences

fn clone(&self) -> AccessibilityPreferences

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for AccessibilityPreferences

impl Debug for AccessibilityPreferences

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

Formats the value using the given formatter.

impl Default for AccessibilityPreferences

fn default() -> AccessibilityPreferences

Returns the “default value” for a type.

impl Eq for AccessibilityPreferences

impl PartialEq for AccessibilityPreferences

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