Struct DiscretePalette 

pub struct DiscretePalette {
    pub meta: ColormapMeta,
    pub colors: &'static [[u8; 3]],
}

A discrete palette of distinct colors for categorical data.

Unlike Colormap, a DiscretePalette has a fixed set of colors and does not interpolate between them.

Fields

meta: ColormapMeta

colors: &'static [[u8; 3]]

Implementations

impl DiscretePalette

pub fn get(&self, i: usize) -> Color

Number of distinct colors in the palette.

pub fn is_empty(&self) -> bool

Returns true if the palette contains no colors.

pub fn all_colors(&self) -> Vec<Color>

All colors as a Vec.
