1. data MaybeFields fields

   opaleye	Opaleye.Internal.MaybeFields

   The Opaleye analogue of Maybe. A value of type MaybeFields a either contains a value of type a, or it contains nothing.

2. MaybeFields :: Column SqlBool -> fields -> MaybeFields fields

   opaleye	Opaleye.Internal.MaybeFields

   No documentation available.

3. module Opaleye.MaybeFields

   MaybeFields is Opaleye's analogue to Maybe. You probably won't want to create values of type MaybeFields directly; instead they will appear as the result of left/right/outer join-like operations, such as optionalRestrict and optional.

4. data MaybeFields fields

   opaleye	Opaleye.MaybeFields

   The Opaleye analogue of Maybe. A value of type MaybeFields a either contains a value of type a, or it contains nothing.

5. newtype MaybeVoid# (a :: ZeroBitType)

   unlifted	Data.Maybe.Void

   Unboxed variant of Maybe. The thing possibly contained by Just has a void runtime representation. Rather than using a sum, like the more general Maybe# does, this represents Nothing with 0 and Just with 1. It is recommended that the data constructor not be used directly. Prefer the two pattern synonyms.

6. MaybeVoid# :: forall (a :: ZeroBitType) . Word# -> MaybeVoid# a

   unlifted	Data.Maybe.Void

   No documentation available.

7. newtype MaybeWord16#

   unlifted	Data.Maybe.Word16

   No documentation available.

8. MaybeWord16# :: Word# -> MaybeWord16#

   unlifted	Data.Maybe.Word16

   No documentation available.

9. newtype Maybe# (a :: TYPE r)

   unlifted	Data.Unlifted

   Unboxed variant of Maybe.

10. Maybe# :: forall (r :: RuntimeRep) (a :: TYPE r) . (# (# #) | a #) -> Maybe# a

    unlifted	Data.Unlifted

    No documentation available.
