Encoding

type Encoding = Builder

encodingBytes :: Encoding -> ByteString

array :: Word32 -> Array -> Encoding

Turn an array builder into final value. The first parameter is OID of the element type.

array_foldable :: Foldable foldable => Word32 -> (element -> Maybe Encoding) -> foldable element -> Encoding

A helper for encoding of arrays of single dimension from foldables. The first parameter is OID of the element type.

array_vector :: Word32 -> (element -> Encoding) -> Vector element -> Encoding

A helper for encoding of arrays of single dimension from vectors. The first parameter is OID of the element type.

nullableArray_vector :: Word32 -> (element -> Encoding) -> Vector (Maybe element) -> Encoding

A helper for encoding of arrays of single dimension from vectors. The first parameter is OID of the element type.

hStore_foldable :: Foldable foldable => foldable (Text, Maybe Text) -> Encoding

A polymorphic HSTORE encoder.

hStore_hashMap :: HashMap Text (Maybe Text) -> Encoding

HSTORE encoder from HashMap.

hStore_map :: Map Text (Maybe Text) -> Encoding

HSTORE encoder from Map.
