Crate css_color_parser

Easy-to-use Rust parser for CSS3 color strings.
Lightweight (Doesn't have any dependencies besides std lib).
Reliable (Provides tests, handles all errors to avoid panic!s).

Not 100% spec compliant in the name of convenience (see examples below):
* allows for extra whitespaces
* allows for floats where standard allows percentages only

Examples

use css_color_parser::Color as CssColor;

let transparent_black = CssColor { r: 0, g: 0, b: 0, a: 1.0 };

println!("{:?}", " rgba (255, 128, 12, 0.5)".parse::<CssColor>()
        .unwrap_or(transparent_black));
//Color { r: 255, g: 128, b: 12, a: 0.5 }

println!("{:?}", "#fff".parse::<CssColor>()
    .unwrap_or(transparent_black));
//Color { r: 255, g: 255, b: 255, a: 1 }

println!("{:?}", "#ff0011".parse::<CssColor>()
    .unwrap_or(transparent_black));
//Color { r: 255, g: 0, b: 17, a: 1 }

println!("{:?}", "slateblue".parse::<CssColor>()
    .unwrap_or(transparent_black));
//Color { r: 106, g: 90, b: 205, a: 1 }

println!("{:?}", "blah".parse::<CssColor>()
    .unwrap_or(transparent_black));
//Color { r: 0, g: 0, b: 0, a: 0 } - ColorParseError

println!("{:?}", "ffffff".parse::<CssColor>()
    .unwrap_or(transparent_black));
//Color { r: 0, g: 0, b: 0, a: 0 } - ColorParseError

println!("{:?}", "hsla(900, 15%, 90%, 0.5)".parse::<CssColor>()
    .unwrap_or(transparent_black));
//Color { r: 226, g: 233, b: 233, a: 0.5 }

println!("{:?}", "hsla(900, 15%, 90%)".parse::<CssColor>()
    .unwrap_or(transparent_black));
//Color { r: 0, g: 0, b: 0, a: 0 } - ColorParseError
println!("{:?}", "hsl(900, 15%, 90%)".parse::<CssColor>()
    .unwrap_or(transparent_black));
//Color { r: 226, g: 233, b: 233, a: 1 }

// NOTE: not spec compliant.
println!("{:?}", "hsl(900, 0.15, 90%)".parse::<CssColor>()
   .unwrap_or(transparent_black)); 
//Color { r: 226, g: 233, b: 233, a: 1 }
