Parse color strings from CSS Color Module Level 4. All legacy sRGB forms are supported:

• RGB hexadecimal notations.
• rgb() and rgba() functions.
• hsl() and hsla() functions.
• hwb() function.
• Named colors including the transparent keyword.

The none keyword is supported. "Missing" color components behave identically to zero.

First, add this to your Cargo.toml:

[dependencies]
css-color = "0.2.8"

use css_color::Srgb;

fn main() {
    let lime = Srgb::new(0., 1., 0., 1.);
    assert_eq!(lime, "#0f0".parse().unwrap());
    assert_eq!(lime, "rgb(0 255 0)".parse().unwrap());
    assert_eq!(lime, "rgb(0% 100% 0%)".parse().unwrap());
    assert_eq!(lime, "hsl(120deg 100% 50% / 100%)".parse().unwrap());
    assert_eq!(lime, "hwb(120 0% 0% / 1)".parse().unwrap());
    assert_eq!(lime, "lime".parse().unwrap());
}

The minimum supported Rust version is 1.55. Earlier versions may compile but parsing can reject certain valid numeric values.
