Enum Color 

pub enum Color {
    Default,
    Indexed(u8),
    Rgb(u8, u8, u8),
}

A cell’s foreground or background colour, stored as a reference.

Deliberately exhaustive (#843). Default / Indexed / Rgb is the whole VT colour-reference space, and a consumer that silently ignored a fourth form would draw the wrong colour. Here the compiler forcing the match is the protection rather than the cost, which is the half of #843’s rule that decides against the attribute. Left exhaustive on purpose, not by omission.

Variants

Default

The scheme’s default fg/bg — resolved downstream.

Indexed(u8)

A slot in the 256-colour palette (0..=15 are the named ANSI colours, 16..=255 the cube + greyscale). The renderer maps it to hex.

Rgb(u8, u8, u8)

A direct 24-bit truecolour triple.
