This package provides types and functions to store and manipulate evidence of equality between types.
To take advantage of kind polymorphism when it is available but not require it, it is split into the following primary modules:
Type.Eq: Types and functions which can be kind-polymorphic if
PolyKindsare available, but are specific to kind
Type.Eq.Higher: Kind-monomorphic types and functions of higher kind, up to
* -> * -> *.
Type.Eq.Poly: Combinators that require kind polymorphism. This module is only available if
Major required extensions:
PolyKinds (GHC 7.6+)
Minimum GHC: 6.10
