Struct Style 

pub struct Style { /* private fields */ }

Whether help output is coloured, and which colours the four semantic roles use.

Plain rendering remains available for generated documents and snapshots; process-facing help uses Style::auto. Remap roles with Style::palette.

Implementations

impl Style

pub const PLAIN: Style

Plain text, suitable for a pipe or a generated artifact.

ANSI CSI escapes already present in authored help are removed as well.

pub const COLOURED: Style

ANSI-coloured text, regardless of the output destination.

pub const fn palette(self, palette: Palette) -> Style

Remap the four semantic roles. Plain rendering ignores the palette.

pub fn auto() -> Style

Colour when stdout is a terminal and the environment permits it.

pub fn auto_stderr() -> Style

Colour when stderr is a terminal and the environment permits it.
