Enum Theme 

#[non_exhaustive]
pub enum Theme {
    System,
    Light,
    Dark,
    HighContrastLight,
    HighContrastDark,
    FollowSystem,
}

Upstream’s supported schemes. System inherits the user’s preference.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

System

Follow the surrounding theme and system preference.

Light

Light scheme.

Dark

Dark scheme.

HighContrastLight

High-contrast light scheme.

HighContrastDark

High-contrast dark scheme.

FollowSystem

Follow the user’s system preference even inside a root that sets a scheme; Theme::System inherits the surrounding one instead.
