Enum Appearance 

pub enum Appearance {
    Unknown,
    Light,
    Dark,
}

The OS light/dark setting. Unknown is a real answer — a host with no way to ask says it, and a view that has one palette per appearance picks its own default for it rather than being handed a guess.

Variants

Unknown

Light

Dark

Implementations

impl Appearance

pub const ALL: &'static [Appearance]

Wire order: the index is the code C passes and the position in schema::APPEARANCES, so unknown is 0 and a zeroed C host means what it says.

pub fn name(self) -> &'static str

pub fn parse(name: &str) -> Option<Appearance>

pub fn code(self) -> u32

The code a C host passes; unknown is 0.

pub fn from_code(code: u32) -> Option<Appearance>

A code past the end is None — ignored rather than folded onto a real appearance, the way an unknown role code is.
