Struct Style 

pub struct Style { /* private fields */ }

Whether to colour, and what with.

The codes are clap’s, so that a terminal shows the same thing: bold red for error:, yellow for the offending text, green for a suggestion and for what was expected, bold underline for Usage:.

Implementations

impl Style

pub const PLAIN: Style

Plain text, for a pipe or a test.

pub const COLOURED: Style

Coloured, whatever the terminal is.

pub fn auto() -> Style

Colour when stderr is a terminal and the environment has not asked otherwise.

NO_COLOR wins over everything, per the convention: a user who sets it has said once, for every program, that they do not want this. CLICOLOR_FORCE is the other direction, for a pipe that ends up somewhere that does render colour.
