# Kleene logic within Rust's type system

[![Build Status](https://travis-ci.org/llogiq/ternary.svg)](https://travis-ci.org/llogiq/ternary)

[![Current Version](http://meritbadge.herokuapp.com/ternary)](https://crates.io/crates/ternary)

[![Coverage Status](https://coveralls.io/repos/github/llogiq/ternary/badge.svg?branch=master)](https://coveralls.io/github/llogiq/ternary?branch=master)

Values are `True`, `False` and `Unknown`. Operations are `Not`, `BitAnd`

and `BitOr` from `std::ops`. There is also the `Ternary` enum which 

represents the values at runtime and the `ToTernary` trait that adds the

`to_ternary()` methods to our value types.

For more information read the [API documentation](http://llogiq.github.io/ternary)

Examples:

`Same` and `Not`

```

 use ternary::{True, False, Unknown, Same};

 use std::ops::Not;

type NotTrue = <::Output as Same>::Output;

type NotFalse = <::Output as Same>::Output;

type NotUnknown = <::Output as Same>::Output;

```

Transforming Values to Runtime, `BitAnd` and `BitOr`

```

assert_eq!(Ternary::T, >::Output>>::Output::to_ternary());

```

To use it, add `ternary = "0.1.0"` to your dependencies.
