Installation

sh $ cargo add heckcheck

Examples

This is a basic roundtrip test for an RGB serializer and parser, which ensures that the output matches the original input.

```rust use heckcheck::prelude::*;

/// A color value encoded as Red-Green-Blue

[derive(Clone, Debug, Arbitrary, PartialEq)]

pub struct Rgb { pub r: u8, pub g: u8, pub b: u8, }

impl Rgb { /// Convert from RGB to Hexadecimal. pub fn to_hex(&self) -> String { format!("#{:02X}{:02X}{:02X}", self.r, self.g, self.b) }

/// Convert from Hexadecimal to RGB.
pub fn from_hex(s: String) -> Self {
    let s = s.strip_prefix('#').unwrap();
    Rgb {
        r: u8::from_str_radix(&s[0..2], 16).unwrap(),
        g: u8::from_str_radix(&s[2..4], 16).unwrap(),
        b: u8::from_str_radix(&s[4..6], 16).unwrap(),
    }
}

}

// Validate values can be converted from RGB to Hex and back. heckcheck::check(|rgb: Rgb| { let hex = rgb.tohex(); let res = Rgb::fromhex(hex); assert_eq!(rgb, res); Ok(()) }); ```

Safety

This crate uses #![deny(unsafe_code)] to ensure everything is implemented in 100% Safe Rust.
