run :: Encoder a -> a -> ByteString Source #
Value encoder
A UTF-8-encoded char.
Note that since it's UTF-8-encoded not the "char" but the "text" OID should be used with it.
hstore :: (forall a. (a -> (Text, Maybe Text) -> a) -> a -> b -> a) -> Encoder b Source #
A polymorphic in-place HSTORE encoder.
Accepts:
- An implementation of the
foldlfunction (e.g.,Data.Foldable.), which determines the input value.foldl'
Here's how you can use it to produce a specific encoder:
hashMapHStore :: Encoder (Data.HashMap.Strict.HashMap Text (Maybe Text)) hashMapHStore = hstore foldl'
Array encoder
data ArrayEncoder a Source #
arrayValue :: Encoder a -> ArrayEncoder a Source #
arrayNullableValue :: Encoder a -> ArrayEncoder (Maybe a) Source #
arrayDimension :: (forall a. (a -> b -> a) -> a -> c -> a) -> ArrayEncoder b -> ArrayEncoder c Source #
