[Rust](https://www.rust-lang.org/) library for parsing CSS color string as defined in the W3C's [CSS Color Module Level 4](https://www.w3.org/TR/css-color-4/).
## Supported Color Format
* [Named colors](https://www.w3.org/TR/css-color-4/#named-colors)
* RGB hexadecimal (with and without `#` prefix)
+ Short format `#rgb`
+ Short format with alpha `#rgba`
+ Long format `#rrggbb`
+ Long format with alpha `#rrggbbaa`
* `rgb()` and `rgba()`
* `hsl()` and `hsla()`
* `hwb()`
* `lab()`
* `lch()`
* `oklab()`
* `oklch()`
* `hwba()`, `hsv()`, `hsva()` - not in CSS standard.
## Usage
Add this to your `Cargo.toml`
```toml
csscolorparser = "0.7"
```
## Examples
Using `csscolorparser::parse()` function.
```rust
let c = csscolorparser::parse("rgb(100%,0%,0%)")?;
assert_eq!(c.to_array(), [1.0, 0.0, 0.0, 1.0]);
assert_eq!(c.to_rgba8(), [255, 0, 0, 255]);
assert_eq!(c.to_css_hex(), "#ff0000");
assert_eq!(c.to_css_rgb(), "rgb(255 0 0)");
assert_eq!(c.name(), Some("red"));
```
Using `parse()` method on `&str`.
```rust
use csscolorparser::Color;
let c: Color = "#ff00007f".parse()?;
assert_eq!(c.to_rgba8(), [255, 0, 0, 127]);
assert_eq!(c.to_css_hex(), "#ff00007f");
```
## Features
### Default
* __named-colors__: Enables parsing from [named colors](https://www.w3.org/TR/css-color-4/#named-colors). Requires [`phf`](https://crates.io/crates/phf). Can be disabled using `default-features = false`.
### Optional
* __lab__: Enables parsing `lab()` and `lch()` color format.
* __rust-rgb__: Enables converting from [`rgb`](https://crates.io/crates/rgb) crate types into `Color`.
* __cint__: Enables converting [`cint`](https://crates.io/crates/cint) crate types to and from `Color`.
* __serde__: Enables serializing (into HEX string) and deserializing (from any supported string color format) using [`serde`](https://serde.rs/) framework.
