  1. foldMap :: (MonoFoldable mono, Monoid m) => (Element mono -> m) -> mono -> m

    mono-traversable Data.MonoTraversable.Unprefixed

    Synonym for ofoldMap

  2. foldMap1Ex :: (MonoFoldable mono, Semigroup m) => (Element mono -> m) -> mono -> m

    mono-traversable Data.MonoTraversable.Unprefixed

    Synonym for ofoldMap1Ex

  3. ofoldMap1 :: (MonoFoldable mono, Semigroup m) => (Element mono -> m) -> NonNull mono -> m

    mono-traversable Data.NonNull

    Map each element of a monomorphic container to a semigroup, and combine the results. Safe version of ofoldMap1Ex, only works on monomorphic containers wrapped in a NonNull.

    Examples

    > let xs = ncons ("hello", 1 :: Integer) [(" world", 2)]
> ofoldMap1 fst xs
"hello world"

  4. conversionMap :: (Ok a -> Ok b) -> Conversion a -> Conversion b

  6. HStoreMap :: Map Text Text -> HStoreMap

    postgresql-simple Database.PostgreSQL.Simple.HStore

  7. fromHStoreMap :: HStoreMap -> Map Text Text

    postgresql-simple Database.PostgreSQL.Simple.HStore

    No documentation available.

  9. BimapCodec :: forall oldOutput output input oldInput context . (oldOutput -> Either String output) -> (input -> oldInput) -> Codec context oldInput oldOutput -> Codec context input output

    autodocodec Autodocodec

    Map a codec in both directions. This is not strictly dimap, because the decoding function is allowed to fail, but we can implement dimap using this function by using a decoding function that does not fail. Otherwise we would have to have another constructor here.

  10. HashMapCodec :: forall k input v output . (Eq k, Hashable k, FromJSONKey k, ToJSONKey k, Coercible input (HashMap k v), Coercible output (HashMap k v)) => JSONCodec v -> Codec Value input output

    autodocodec Autodocodec

    Encode a HashMap, and decode any HashMap.
