data FieldEncoder a

A FieldEncoder for a type a consists of a function from a to it's binary representation, and an Postgres OID which tells Postgres it's type & how to decode it.

Constructors

FieldEncoder Oid (a -> Builder)

Instances

Contravariant FieldEncoder

Defined in Preql.Wire.ToSql

Methods

contramap :: (a -> b) -> FieldEncoder b -> FieldEncoder a

(>$) :: b -> FieldEncoder b -> FieldEncoder a

runFieldEncoder :: FieldEncoder p -> p -> (Oid, ByteString)

type RowEncoder a = a -> [(Oid, ByteString)]

runEncoder :: RowEncoder p -> p -> [Maybe (Oid, ByteString, Format)]

oneField :: FieldEncoder a -> RowEncoder a

class ToSqlField a where

Types which can be encoded to a single Postgres field.
