Enum CupertinoUserInterfaceLevelData 

pub enum CupertinoUserInterfaceLevelData {
    Base,
    Elevated,
}

How high a piece of interface sits: on the window’s own surface, or raised above it — a sheet, a dialog, a popover.

An adaptive colour has a variant for each, and in a dark interface they differ: the background of a raised sheet is a little lighter than the page under it, which is how a dark interface shows depth without shadows. In a light one they are nearly all the same.

A subtree says which it is with around; the theme carries the answer (Theme::user_interface_level), and CupertinoDynamicColor::resolve reads it there.

Variants

Base

The window’s own surface. What everything is, until something says otherwise.

Elevated

Raised above it: a sheet, a dialog, a popover.

Implementations

impl CupertinoUserInterfaceLevelData

pub fn around<Msg: 'static>( self, child: impl Widget<Msg> + 'static, ) -> Themed<Msg>

Wraps child in this level: the adaptive colours inside it resolve to this level’s variants.

pub fn of(theme: &Theme) -> Self

The level theme says its subtree is at.
