Type equalities for F#

This library contains type equalities (Teqs) for F#. These equalities allow us to create type-safe abstractions by allowing us to encode Generalised Algebraic Data Types (GADTs), as found in languages like Haskell.

Usage

To use Teqs in your projects, you'll want to reference the main TypeEquality project. The project is available as a nuget package - https://www.nuget.org/packages/TypeEquality.
This project provides a type Teq<'a,'b> of proofs that 'a and 'b are the same type. By including these in the declaration of a generic discriminated union, you can constrain the types each case applies to, encoding a GADT. An example of this may be found in the Example folder.

For more advanced usage, TypeEquality also allows you to reason about Teqs using the functions in the Teq and Teq.Cong (congruence) modules.

The library has some unit tests in the Test/TypeEquality.Test.fsproj project.
