  1. maybeFields :: Default IfPP b b => b -> (a -> b) -> MaybeFields a -> b

    opaleye Opaleye.Internal.MaybeFields

    The Opaleye analogue of maybe

  2. maybeFieldsExplicit :: IfPP b b' -> b -> (a -> b) -> MaybeFields a -> b'

    opaleye Opaleye.Internal.MaybeFields

    No documentation available.

  3. maybeFieldsToNullable :: MaybeFields (Field a) -> FieldNullable a

    opaleye Opaleye.Internal.MaybeFields

    Convert nothingFields to NULL to a justFields to non-NULL

  4. maybeFieldsToSelect :: SelectArr (MaybeFields a) a

    opaleye Opaleye.Internal.MaybeFields

    The Opaleye analogue of maybeToList. Unless you are using arrow notation you'll probably find catMaybeFields easier to use.

  5. maybeFields :: Default IfPP b b => b -> (a -> b) -> MaybeFields a -> b

    opaleye Opaleye.MaybeFields

    The Opaleye analogue of maybe

  6. maybeFieldsExplicit :: IfPP b b' -> b -> (a -> b) -> MaybeFields a -> b'

    opaleye Opaleye.MaybeFields

    No documentation available.

  7. maybeFieldsToNullable :: MaybeFields (Field a) -> FieldNullable a

    opaleye Opaleye.MaybeFields

    Convert nothingFields to NULL to a justFields to non-NULL

  8. maybeFieldsToSelect :: SelectArr (MaybeFields a) a

    opaleye Opaleye.MaybeFields

    The Opaleye analogue of maybeToList. Unless you are using arrow notation you'll probably find catMaybeFields easier to use.

  9. maybeReader :: (String -> Maybe a) -> Reader a

    opt-env-conf OptEnvConf

    Turn a Maybe parsing function into a Reader

  10. maybeReader :: (String -> Maybe a) -> Reader a

    opt-env-conf OptEnvConf.Reader

    Turn a Maybe parsing function into a Reader
