pub fn force_colour() -> Result<(), AlreadySet>Expand description
Inject ANSI colour escape codes into the output, regardless of the value of the NO_COLOR
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.
ยงErrors
Returns an error if this library has already been initialised to not inject ANSI colour escape
codes, e.g. by calling force_no_colour of calling one of the macros where the environment
was detected to require no coloured output.
