1. module Database.Record.Persistable

   This module defines proposition interfaces for database value type and record type width.

2. type PersistableRecordWidth a = ProductConst Sum Int a

   persistable-record	Database.Record.Persistable

   Proposition to specify width of Haskell type a. The width is length of database value list which is converted from Haskell type a.

3. data PersistableSqlType q

   persistable-record	Database.Record.Persistable

   Proposition to specify type q is database value type, contains null value

4. class Eq q => PersistableType q

   persistable-record	Database.Record.Persistable

   Interface of derivation rule for PersistableSqlType.

5. class PersistableWidth a

   persistable-record	Database.Record.Persistable

   PersistableWidth a is implicit rule to derive PersistableRecordWidth a width proposition for type a. Generic programming (https://downloads.haskell.org/~ghc/latest/docs/html/users_guide/glasgow_exts.html#generic-programming) with default signature is available for PersistableWidth class, so you can make instance like below:

   {-# LANGUAGE DeriveGeneric #-}
   import GHC.Generics (Generic)
   --
   data Foo = Foo { ... } deriving Generic
   instance PersistableWidth Foo
   

6. module Database.HDBC.Record.Persistable

   This module provides HDBC instance definitions of DB-record.

7. module Database.HDBC.PostgreSQL.Persistable

   This module defines Persistable instances for PostgreSQL types

8. module Database.Persist.Monad.Internal.PersistentShim

   No documentation available.

9. PersistArray :: [PersistValue] -> PersistValue

   persistent-mtl	Database.Persist.Sql.Shim

   Intended especially for PostgreSQL backend for text arrays

10. PersistBool :: Bool -> PersistValue

    persistent-mtl	Database.Persist.Sql.Shim

    No documentation available.
