Bug or user error?

[Algorab]

Try to convert from the hsl colorspace to the rgb colorspace and don't get the
expected values. Not sure is it a bug or a user error.

cargo play script

//# palette = "0.6.0"
use palette;
use palette::{Hsl, RgbHue, FromColor};
use palette::rgb::Rgb;

fn main() {

    let degrees = 60.0;
    let saturation = 100.0;
    let lightness = 50.0;

    let hsl: Hsl = Hsl::from_components((RgbHue::from_degrees(degrees), saturation, lightness));
    let rgb: Rgb = Rgb::from_color(hsl);

    println!("{:?}", rgb);

    //Expect RGB values for yellow
    assert_eq!(rgb.red, 255.0, "expect for red 255");
    assert_eq!(rgb.green, 255.0, "expect for green 255");
    assert_eq!(rgb.blue, 0.0, "expect for blue 0");

}

It looks to me like it's just a matter of using different scales (there are multiple conventions). The ranges of RGB, saturation and lightness is 0.0 to 1.0 when using f32 and f64. So if I'm reading this correctly, saturation should be 1.0, lightness should be 0.5 and the expected RGB values either changed from 255.0 to 1.0 or converted to u8 with some variant of rgb.into_format::<u8>().

You can check the documentation for the ranges of each color space.

You are completely right. After applying what you mentioned, it works as I expect.
Thanks a lot.
