#[non_exhaustive]
pub enum ColorMode {
    Auto,
    On,
    Off,
}
Expand description

A configuration option that determines if format will be colorful.

The default is ColorMode::Auto, which only enables color if stdout is detected to be a shell terminal (tty). If this detection is incorrect, you can explicitly set it to ColorMode::On or ColorMode::Off

Note: The actual colorization of output is determined by the log formatters, so it is possible for this to be correctly enabled but for the output to have no colored components.
