CoAxiom

Description

Module for coercion axioms, used to represent type family instances and newtypes

Synopsis

Documentation

type Branched = Branched Source #

type Unbranched = Unbranched Source #

mapAccumBranches :: ([CoAxBranch] -> CoAxBranch -> CoAxBranch) -> Branches br -> Branches br Source #

The [CoAxBranch] passed into the mapping function is a list of all previous branches, reversed

data CoAxiom br Source #

A CoAxiom is a "coercion constructor", i.e. a named equality axiom.
