Enum ansi_term::Colour

Black

Colour #0 (foreground code 30, background code 40).

This is not necessarily the background colour, and using it as one may render the text hard to read on terminals with dark backgrounds.

Red

Colour #1 (foreground code 31, background code 41).

Green

Colour #2 (foreground code 32, background code 42).

Yellow

Colour #3 (foreground code 33, background code 43).

Blue

Colour #4 (foreground code 34, background code 44).

Purple

Colour #5 (foreground code 35, background code 45).

Cyan

Colour #6 (foreground code 36, background code 46).

White

Colour #7 (foreground code 37, background code 47).

As above, this is not necessarily the foreground colour, and may be hard to read on terminals with light backgrounds.

Fixed(u8)

A colour number from 0 to 255, for use in 256-colour terminal environments.

Colours 0 to 7 are the Black to White variants respectively. These colours can usually be changed in the terminal emulator.
Colours 8 to 15 are brighter versions of the eight colours above. These can also usually be changed in the terminal emulator, or it could be configured to use the original colours and show the text in bold instead. It varies depending on the program.
Colours 16 to 231 contain several palettes of bright colours, arranged in six squares measuring six by six each.
Colours 232 to 255 are shades of grey from black to white.

It might make more sense to look at a colour chart.

RGB(u8, u8, u8)

A 24-bit RGB color, as specified by ISO-8613-3.

Implementations§

impl Colour

pub fn prefix(self) -> Prefix

The prefix bytes for this colour as a Style. These are the bytes that tell the terminal to use a different colour or font style.

Examples

use ansi_term::Colour::Green;

assert_eq!("\x1b[0m",
           Green.suffix().to_string());

pub fn infix(self, next: Colour) -> Infix

The infix bytes between this colour and next colour. These are the bytes that tell the terminal to use the next colour, or to do nothing if the two colours are equal.

Examples

use ansi_term::Colour::{Red, Yellow};

assert_eq!("\x1b[33m",
           Red.infix(Yellow).to_string());

pub fn suffix(self) -> Suffix

The suffix for this colour as a Style. These are the bytes that tell the terminal to reset back to its normal colour and font style.

Examples

use ansi_term::Colour::Purple;

assert_eq!("\x1b[0m",
           Purple.suffix().to_string());

impl Colour

pub fn normal(self) -> Style

Returns a Style with the foreground colour set to this colour.

Examples

use ansi_term::Colour;

let style = Colour::Red.normal();
println!("{}", style.paint("hi"));

pub fn bold(self) -> Style

Returns a Style with the foreground colour set to this colour and the bold property set.

Examples

use ansi_term::Colour;

let style = Colour::Green.bold();
println!("{}", style.paint("hey"));

pub fn dimmed(self) -> Style

Returns a Style with the foreground colour set to this colour and the dimmed property set.

Examples

use ansi_term::Colour;

let style = Colour::Yellow.dimmed();
println!("{}", style.paint("sup"));

pub fn italic(self) -> Style

Returns a Style with the foreground colour set to this colour and the italic property set.

Examples

use ansi_term::Colour;

let style = Colour::Blue.italic();
println!("{}", style.paint("greetings"));

pub fn underline(self) -> Style

Returns a Style with the foreground colour set to this colour and the underline property set.

Examples

use ansi_term::Colour;

let style = Colour::Purple.underline();
println!("{}", style.paint("salutations"));

pub fn blink(self) -> Style

Returns a Style with the foreground colour set to this colour and the blink property set.

Examples

use ansi_term::Colour;

let style = Colour::Cyan.blink();
println!("{}", style.paint("wazzup"));

pub fn reverse(self) -> Style

Returns a Style with the foreground colour set to this colour and the reverse property set.

Examples

use ansi_term::Colour;

let style = Colour::Black.reverse();
println!("{}", style.paint("aloha"));

pub fn hidden(self) -> Style

Returns a Style with the foreground colour set to this colour and the hidden property set.

Examples

use ansi_term::Colour;

let style = Colour::White.hidden();
println!("{}", style.paint("ahoy"));

pub fn strikethrough(self) -> Style

Returns a Style with the foreground colour set to this colour and the strikethrough property set.

Examples

use ansi_term::Colour;

let style = Colour::Fixed(244).strikethrough();
println!("{}", style.paint("yo"));

pub fn on(self, background: Colour) -> Style

Returns a Style with the foreground colour set to this colour and the background colour property set to the given colour.

Examples

use ansi_term::Colour;

let style = Colour::RGB(31, 31, 31).on(Colour::White);
println!("{}", style.paint("eyyyy"));

impl Colour

pub fn paint<'a, I, S: 'a + ToOwned + ?Sized>(
 self,
 input: I
) -> ANSIGenericString<'a, S>where
 I: Into<Cow<'a, S>>,
 <S as ToOwned>::Owned: Debug,

Paints the given text with this colour, returning an ANSI string. This is a short-cut so you don’t have to use Blue.normal() just to get blue text.

use ansi_term::Colour::Blue;
println!("{}", Blue.paint("da ba dee"));
