Struct CellColor 

pub struct CellColor(/* private fields */);

One packed color value. All-zero = terminal default (no escape).

Implementations

impl CellColor

pub const DEFAULT: CellColor

Terminal default — no escape emitted.

pub const fn ansi256(index: u8) -> CellColor

An ANSI-256 palette color.

pub const fn rgb(r: u8, g: u8, b: u8) -> CellColor

A 24-bit RGB color.

pub fn is_set(self) -> bool

Whether this is a real color (an escape will be emitted).

pub fn as_ansi256(self) -> Option<u8>

This color as an ANSI-256 index, quantizing RGB if needed. Returns None for CellColor::DEFAULT (the consumer’s “no color set” — use its own default ink).

pub fn as_rgb(self) -> Option<(u8, u8, u8)>

This color as RGB, expanding an ANSI index if needed. Returns None for CellColor::DEFAULT (the consumer’s “no color set” — use its own default ink). This is what an SVG/TUI consumer feeds its own color model.
