Data.Sv.Encode.Type

Description

The core type for encoding

Synopsis

Documentation

newtype Encode a Source #

An Encode converts its argument into one or more textual fields, to be written out as CSV.

It is Semigroup, Monoid, Contravariant, Divisible, and Decidable, allowing for composition of these values to build bigger Encodes from smaller ones.

(<>) :: Encode a -> Encode a -> Encode a #

sconcat :: NonEmpty (Encode a) -> Encode a #

Defined in Data.Sv.Encode.Type

Methods

mempty :: Encode a #

mappend :: Encode a -> Encode a -> Encode a #

mconcat :: [Encode a] -> Encode a #

newtype NameEncode a Source #

A NameEncode is an Encode with an attached column name.

It is Semigroup, Monoid, Contravariant, and Divisible, allowing for composition of these values to build bigger NameEncodes from smaller ones.

Notably, NameEncode is not Decidable, since taking the sum of column names does not make sense.
