Description

generics-eot tries to be a library for datatype generic programming that is easy to understand. "eot" stands for "eithers of tuples".

A tutorial on how to use generics-eot can be found here: https://generics-eot.readthedocs.io/.

Documentation

class HasEot a where Source #

An instance (HasEot a) allows us to

convert values of an arbitrary algebraic datatype a to and from a generic representation (Eot a) (see toEot and fromEot).
extract meta information about the type a (see datatype).

Once an algebraic datatype has an instance for Generic it automatically gets one for HasEot.

Associated Types

type Eot a Source #

Eot is a type level function that maps arbitrary ADTs to isomorphic generic representations. Here's an example:

data Foo = A Int Bool | B String

would be mapped to:

Either (Int, (Bool, ())) (Either (String, ()) Void)

These representations follow these rules:

The choice between constructors is mapped to right-nested Eithers.
There's always a so-called end-marker Void. It's an invalid choice (and Void is uninhabited to make sure you don't accidentally create such a value). So e.g. data Foo = A would be mapped to Either () Void, and a type with no constructors is mapped to Void.
The fields of one constructor are mapped to right-nested tuples.
Again there's always an end-marker, this time of type (). A constructor with three fields a, b, c is mapped to (a, (b, (c, ()))), one field a is mapped to (a, ()), and no fields are mapped to () (just the end-marker).

These rules (and the end-markers) are necessary to make sure generic functions know exactly which parts of the generic representation are field types and which parts belong to the generic skeleton.

Methods

toEot :: a -> Eot a Source #

Convert a value of type a to its generic representation.

fromEot :: Eot a -> a Source #

Convert a value in a generic representation to a (inverse of toEot).

data Proxy (t :: k) #

Proxy is a type that holds no data, but has a phantom parameter of arbitrary type (or even kind). Its use is to provide type information, even though there is no value available of that type (or it may be too costly to create one).

Historically, Proxy :: Proxy a is a safer alternative to the undefined :: a idiom.

>>> Proxy :: Proxy (Void, Int -> Int)
Proxy

Proxy can even hold types of higher kinds,

>>> Proxy :: Proxy Either
Proxy

>>> Proxy :: Proxy Functor
Proxy

>>> Proxy :: Proxy complicatedStructure
Proxy
