Enum cursive_core::theme::Color

pub enum Color {
    TerminalDefault,
    Dark(BaseColor),
    Light(BaseColor),
    Rgb(u8, u8, u8),
    RgbLowRes(u8, u8, u8),
}

Represents a color used by the theme.

Variants

TerminalDefault

Represents a color, preset by terminal.

Dark(BaseColor)

One of the 8 base colors.

These colors should work on any terminal.

Note: the actual color used depends on the terminal configuration.

Light(BaseColor)

Lighter version of a base color.

The native linux TTY usually doesn’t support these colors, but almost all terminal emulators should.

Note: the actual color used depends on the terminal configuration.

Rgb(u8, u8, u8)

True-color, 24-bit.

On terminals that don’t support this, the color will be “downgraded” to the closest one available.

RgbLowRes(u8, u8, u8)

Low-resolution color.

Each value should be <= 5 (you’ll get panics otherwise).

These 216 possible colors are part of the terminal color palette (256 colors).

Implementations

impl Color

pub fn from_256colors(n: u8) -> Self

Creates a color from its ID in the 256 colors list.

• Colors 0-7 are base dark colors.
• Colors 8-15 are base light colors.
• Colors 16-231 are rgb colors with 6 values per channel (216 colors).
• Colors 232-255 are grayscale colors.

pub fn low_res(r: u8, g: u8, b: u8) -> Option<Self>

Creates a Color::RgbLowRes from the given values for red, green and blue.

Returns None if any of the values exceeds 5.

pub fn parse(value: &str) -> Option<Self>

Parse a string into a color.

Examples:

• "red" becomes Color::Dark(BaseColor::Red)
• "light green" becomes Color::Light(BaseColor::Green)
• "default" becomes Color::TerminalDefault
• "#123456" becomes Color::Rgb(0x12, 0x34, 0x56)

Trait Implementations

impl Clone for Color

fn clone(&self) -> Color

Returns a copy 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 From<Color> for ColorStyle

fn from(color: Color) -> Self

Converts to this type from the input type.

impl From<Color> for ColorType

fn from(color: Color) -> Self

Converts to this type from the input type.

impl From<Color> for Style

fn from(color: Color) -> Self

Converts to this type from the input type.

impl Hash for Color

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)where
    H: Hasher,
    Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq<Color> for Color

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

This method tests for self and other values to be equal, and is used by ==.

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

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