-- | This module exports many types and functions for operating on
-- @persistent@'s database representation. It's a bit of a kitchen sink. In the
-- future, this module will be reorganized, and many of the dependent modules
-- will be viewable on their own for easier documentation and organization.

-- * Various Types of Names
-- | There are so many kinds of names. @persistent@ defines newtype wrappers
-- for 'Text' so you don't confuse what a name is and what it is
-- supposed to be used for
module Database.Persist.Names
-- * Database Definitions
-- ** Entity/Table Definitions
-- | The 'EntityDef' type is used by @persistent@ to generate Haskell code,
-- generate database migrations, and maintain metadata about entities. These
-- are generated in the call to 'Database.Persist.TH.mkPersist'.
, module Database.Persist.EntityDef
-- ** Field definitions
-- | The 'FieldDef' type is used to describe how a field should be
-- represented at the Haskell and database layers.
, module Database.Persist.FieldDef
-- * Intermediate Values
-- | The 'PersistValue' type is used as an intermediate layer between
-- database and Haskell types.
