Struct AccessibilityOverrides 

pub struct AccessibilityOverrides {
    pub bold_text: Option<bool>,
    pub high_contrast: Option<bool>,
    pub disable_animations: Option<bool>,
    pub invert_colors: Option<bool>,
    pub accessible_navigation: Option<bool>,
    pub always_use_24_hour_format: Option<bool>,
}

What an application wants to say about Accessibility instead of the platform, one setting at a time.

Every field is an Option, and None is an answer: this application has no opinion, use what the user’s system reports. That distinction is the whole point of the type. A plain Accessibility cannot make it — a false there is indistinguishable from silence, so an application that only wanted to force reduce motion would also be telling the framework that its user does not use a screen reader.

It is the same shape, and the same reason, as TextStyle against ResolvedTextStyle: one type asks, the other answers.

fn accessibility(&self) -> AccessibilityOverrides {
    // A settings screen with a "reduce motion" switch of its own. Everything else
    // still comes from the platform.
    AccessibilityOverrides::NONE.disable_animations(self.reduce_motion)
}
