Function cichlid::rgb_gradient

pub fn rgb_gradient<'a, C: 'a + From<ColorRGB>, I: IntoIterator<Item = &'a mut C>>(
    output: I, 
    length: usize, 
    start: ColorRGB, 
    end: ColorRGB
)

Creates a two-color gradient from two RGB values.

This function will fill the array inclusive of the start RGB and exclusive of the end RGB. This means that after completion, output[output.len() - 1] will not be the end color, but rather the interpolated color before start`.

Edge Cases

If output is empty, the operation returns immediately.
