Enum Card 

#[non_exhaustive]
pub enum Card {
    Text {
        line: String,
        ink: Rgb,
        background: Rgb,
    },
    Picture {
        path: String,
        background: Rgb,
    },
}

What the screen shows while the game’s data loads, from the first frame (a slow device takes seconds to load a game, and shows nothing until a frame is drawn). Drawn by the backend with what it has of its own, since the game’s font isn’t loaded yet.

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.

Text

A line of text (the game’s name, say), centred, in the backend’s own font.

Fields

line: String

The line.

ink: Rgb

Its colour.

background: Rgb

The colour of the rest of the screen.

Picture

A picture from the game’s files, by path, centred at the largest whole scale that fits.

Fields

path: String

Its path among the game’s files.

background: Rgb

The colour of the rest of the screen.
