Generic.Data.Types

Description

Utilities to derive and transform generic types.

Synopsis

newtype Data r p = Data {
- unData :: r p
}
toData :: Generic a => a -> Data (Rep a) p
fromData :: Generic a => Data (Rep a) p -> a

Documentation

newtype Data r p Source #

Synthetic data type.

A wrapper to view a generic Rep as the datatype it's supposed to represent, without needing a declaration.

Constructors

Fields unData :: r p
