Struct charts::color::Color

pub struct Color {
    pub r: u8,
    pub g: u8,
    pub b: u8,
}

RGBA color.

Fields

r: u8

Red component.

g: u8

Green component.

b: u8

Blue component.

Implementations

impl Color

pub fn new(r: u8, g: u8, b: u8) -> Self

Color constructor.

Examples

let color = Color::new(0xff, 0x00, 0x00);
assert_eq!(&color.to_string(), "#ff0000")

pub const BLACK: Self = _

Black.

pub fn from_str<Str: AsRef<str>>(text: Str) -> Res<Self>

Constructs a color from a string.

• only accepts RGB strings starting with #.

Examples

let color = Color::from_str("#ff0000").unwrap();
assert_eq!(&color.to_string(), "#ff0000")

pub fn to_plotters(&self) -> Rgb<Srgb, u8>

Turns itself in a plotters-compliant color.

pub fn from_hue(hue: f32, saturation: f32, lightness: f32) -> Self

Constructor from hue quantity.

pub fn randoms(n: usize) -> Vec<Self>

Constructs n random colors evenly spread on the color wheel.

• the starting point on the color wheel is random.

Guarantees

• Color::randoms(n).len() == n

pub fn random() -> Self

Constructs a random color.

• dark indicates whether the random color should be relatively dark.

pub fn random_until(pred: impl Fn(&Color) -> bool) -> Self

Keeps on constructing colors until the input predicate is true.

pub fn is_similar_to(&self, other: &Self) -> bool

Returns true if two colors are very similar.

“Very similar” here means that all components are less than 15u8 apart.
