Enum Brightness 

pub enum Brightness {
    Light,
    Dark,
}

Re-export: size classes and orientation, so the application can drive its own responsive behaviour. Whether a surface is showing a light or a dark interface.

The platform’s own preference, which an application may follow or ignore. It is not the same question as which theme this application is using: a light application on a dark system is a choice, not a mistake.

Variants

Light

A light interface: dark content on a light surface.

Dark

A dark interface: light content on a dark surface.

Implementations

impl Brightness

pub const fn is_dark(self) -> bool

Is this the dark one?

pub const fn is_light(self) -> bool

Is this the light one?

pub const fn inverted(self) -> Brightness

The brightness content on this surface must have to be legible — the opposite of this one. A dark surface takes light content, and the other way round.
