Function colour::force_no_colour

pub fn force_no_colour() -> Result<(), AlreadySet>

Do not inject ANSI colour escape codes into the output, regardless of the value of the CLICOLOR_FORCE environment variable, or whether the output terminal (if any) supports them.

This should normally only be called by a binary application, not a library. It should be called before using any of the print or write macros.

Errors

Returns an error if this library has already been initialised to inject ANSI colour escape codes, e.g. by calling force_colour of calling one of the macros where the environment was detected to require coloured output.
