Description

This module re-exports definitions from Wire.* that are expected to be useful

Synopsis

Decoding rows

class FromSql a where Source #

A type which can be decoded from a SQL row. Note that this includes the canonical order of fields.

The default (empty) instance works for any type with a FromSqlField instance

Minimal complete definition

Nothing

Associated Types

type Width a :: Nat Source #

The number of columns read in decoding this type.

type Width a = 1

Methods

fromSql :: RowDecoder (Width a) a Source #

default fromSql :: (FromSqlField a, Width a ~ 1) => RowDecoder (Width a) a Source #

RowDecoder is Functor but not Monad so that we can index the type by the number of columns that it consumes. We also know & verify all of the OIDs before we read any of the field data sent by Postgres, which would admit an Applicative instance but not Monad
