Enum Color 

pub enum Color {
    Black,
    Red,
    Green,
    Yellow,
    Blue,
    Purple,
    Cyan,
    White,
    Fixed(u8),
    RGB(u8, u8, u8),
    Named(String),
}

A colour is one specific type of ANSI escape code, and can refer to either the foreground or background colour.

These use the standard numeric sequences. See http://invisible-island.net/xterm/ctlseqs/ctlseqs.html

Variants

Black

Color #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

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

Green

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

Yellow

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

Blue

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

Purple

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

Cyan

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

White

Color #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.

• Colors 0 to 7 are the Black to White variants respectively. These colours can usually be changed in the terminal emulator.
• Colors 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.
• Colors 16 to 231 contain several palettes of bright colours, arranged in six squares measuring six by six each.
• Colors 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.

Named(String)

A named color, as supported by tint.

Trait Implementations

impl Clone for Color

fn clone(&self) -> Color

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Color

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for Color

fn default() -> Color

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for Color

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for Color

fn eq(&self, other: &Color) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for Color

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Eq for Color

impl StructuralPartialEq for Color
