[−][src]Enum colored_json::ColorMode
ColorMode is a switch to enforce color mode, turn it off or auto-detect, if it should be used
Variants
Auto(Output)
Methods
impl ColorMode
[src]
With ColorMode
you can implement command line options like --color=auto|on|off
easily.
Example:
let option = "--color=auto"; let color_mode = match option { "--color=on" => ColorMode::Off, "--color=off" => ColorMode::On, _ => ColorMode::default().eval(), }; assert!(match color_mode { ColorMode::On | ColorMode::Off => true, _ => false });
pub fn should_colorize(output: Output) -> bool
[src]
indicates, if the output
is a capable of displaying colors
pub fn eval(self) -> Self
[src]
Returns ColorMode::On or ColorMode::Off
Example:
let on_off = ColorMode::default().eval(); assert!(match on_off { ColorMode::On | ColorMode::Off => true, _ => false });
pub fn use_color(self) -> bool
[src]
Indicates if color should be used
Example:
if ColorMode::default().use_color() { println!("We can use color! :-)"); } else { println!("No color for you! :-("); } if ColorMode::Auto(Output::StdErr).use_color() { println!("We can use color on stderr! :-)"); } else { println!("No color for you on stderr! :-("); } assert_eq!(ColorMode::On.use_color(), true); assert_eq!(ColorMode::Off.use_color(), false);
