Enum ColorMode 

#[non_exhaustive]
pub enum ColorMode {
    Auto,
    Truecolor,
    Ansi256,
    Ansi16,
    Never,
}

Terminal colour capability override for the TUI theme system.

Auto runs OS-level detection at startup; any other value forces the specified mode and skips detection entirely. Resolution is performed once at TUI startup and stored in the TUI App theme.

Example (TOML)

[tui.theme]
color_mode = "truecolor"   # force 24-bit even if $COLORTERM is unset

Examples

use zeph_config::ColorMode;

let mode: ColorMode = toml::from_str("value = \"auto\"")
    .map(|t: toml::Table| t["value"].clone().try_into().unwrap())
    .unwrap();
assert_eq!(mode, ColorMode::Auto);

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.

Auto

Run terminal capability detection at startup (default).

Truecolor

Force 24-bit RGB output; skip capability detection.

Ansi256

Force RGB → xterm-256 downgrade.

Ansi16

Force RGB → ANSI-16 downgrade.

Never

Strip all colour; retain text modifiers only (equivalent to NO_COLOR).
