    patch Data.Patch.PatchOrReplacement

    No documentation available.

  3. data PCREOption

    pcre-heavy Text.Regex.PCRE.Heavy

    A type for PCRE compile-time options. These are newtyped CInts, which can be bitwise-or'd together, using (.|.)

  4. type PersistableRecordWidth a = ProductConst Sum Int a

    persistable-record Database.Record

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

  5. data PersistableSqlType q

    persistable-record Database.Record

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

  6. class Eq q => PersistableType q

    persistable-record Database.Record

    Interface of derivation rule for PersistableSqlType.

  7. class PersistableWidth a

    persistable-record Database.Record

    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

  8. data Primary

    persistable-record Database.Record

    Constraint type. Primary key.

  9. type PrimaryColumnConstraint = ColumnConstraint Primary

    persistable-record Database.Record

    Specialized primary constraint.

  10. type PrimaryConstraint = KeyConstraint Primary

    persistable-record Database.Record

    Specialized primary constraint.
