Enum ColorMode 

#[non_exhaustive]
pub enum ColorMode {
    Auto,
    Always,
    Never,
}

Whether to write colour, as the caller asked.

Always and Never ignore the variables that decide whether to write colour, NO_COLOR, CLICOLOR, CLICOLOR_FORCE, FORCE_COLOR, and TERM=dumb, and ask no stream. The depth and the width still follow their variables. Auto follows the order in the Colour section of the crate docs.

ctl-core’s own ColorMode, which its --color flag parses to, converts into this type with From.

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

Decide from the environment and the stream.

Always

Write colour whatever the environment holds.

Never

Write no colour whatever the environment holds.
