data-category-0.3.0.1: data-category.cabal
name: data-category
version: 0.3.0.1
synopsis: Restricted categories
description: Data-category is a collection of categories, and some categorical constructions on them.
.
You can restrict the types of the objects of your category by using a GADT for the arrow type.
To be able to proof to the compiler that a type is an object in some category, objects also need to be represented at the value level.
The corresponding identity arrow of the object is used for that.
.
See the 'Monoid', 'Boolean' and 'Product' categories for some examples.
.
Note: Strictly speaking this package defines Hask-enriched categories, not ordinary categories (which are Set-enriched.)
In practice this means we are allowed to ignore 'undefined' (f.e. when talking about uniqueness of morphisms),
and we can treat the categories as normal categories.
