Description

Supporting definitions used by both the simple and the advanced interface

To use the anonymous records library, you will want to use either the simple interface in Data.Record.Anon.Simple or the advanced interface in Data.Record.Anon.Advanced. This module provides definitions that are used by both. Moreover, unlike .Simple and .Advanced, this module is designed to be imported unqualified. A typical import section will therefore look something like

import Data.Record.Anon
import Data.Record.Anon.Simple (Record)
import qualified Data.Record.Anon.Simple as Anon

In addition, since the classes and type families defined here as handled by the plugin, you will also want to enable that:

{-# OPTIONS_GHC -fplugin=Data.Record.Anon.Plugin #-}

Rows

pattern (:=) :: a -> b -> Pair a b Source #

type Row k = [Pair Symbol k] Source #

Row: type-level list of field names and corresponding field types

type family Merge :: Row k -> Row k -> Row k Source #

Merge two rows

See merge for detailed discussion.

Constraints

class AllFields (r :: Row k) (c :: k -> Constraint) Source #

Require that c x holds for every (n := x) in r.

Instance details Defined in Data.Record.Anon.Plugin.Internal.Runtime Methods fieldDicts :: DictAllFields k0 r (Compose Ord (K a))

class KnownFields (r :: Row k) Source #

Require that all field names in r are known

class SubRow (r :: Row k) (r' :: Row k) Source #

Subrecords

If SubRow r r' holds, we can project (or create a lens) r to r'. See project for detailed discussion.

class RowHasField (n :: Symbol) (r :: Row k) (a :: k) | n r -> a Source #

Specialized form of HasField

RowHasField n r a holds if there is an (n := a) in r.

Fields

data Field n Source #

Proxy for a field name, with IsLabel instance

The IsLabel instance makes it possible to write

#foo

to mean

Field (Proxy @"foo")

Instances

Instances details

(n ~ n', KnownSymbol n, KnownHash n) => IsLabel n' (Field n) Source #
Instance details Defined in Data.Record.Anon.Internal.Advanced Methods fromLabel :: Field n #

class KnownHash (s :: Symbol) where Source #

Symbol (type-level string) with compile-time computed hash

Instances are computed on the fly by the plugin.

Methods

hashVal :: forall proxy. proxy s -> Int Source #

Type-level metadata

This is primarily for interop with generics-sop.

type family FieldTypes (f :: k -> Type) (r :: Row k) :: [(Symbol, Type)] Source #

Type-level metadata

   FieldTypes Maybe [ "a" := Int, "b" := Bool ]
== [ '("a", Maybe Int), '("b", Maybe Bool) ]

type family SimpleFieldTypes (r :: Row Type) :: [(Symbol, Type)] Source #

Like FieldTypes, but for the simple API (no functor argument)

   SimpleFieldTypes [ "a" := Int, "b" := Bool ]
== [ '("a", Int), '("b", Bool) ]

Type utilities

data Some (f :: k -> Type) where Source #

Existential type ("there exists an x such that f x")

Constructors

Some :: forall k (f :: k -> Type) (x :: k). f x -> Some f

data Reflected c where Source #

Evidence of some constraint c

This is like Dict, but without the functor argument.

Constructors

Reflected :: c => Reflected c

Re-exports

data Product (f :: k -> Type) (g :: k -> Type) (a :: k) #

Lifted product of functors.

Constructors

Pair (f a) (g a)

data Proxy (t :: k) #

Proxy is a type that holds no data, but has a phantom parameter of arbitrary type (or even kind). Its use is to provide type information, even though there is no value available of that type (or it may be too costly to create one).

Historically, Proxy :: Proxy a is a safer alternative to the undefined :: a idiom.

>>> Proxy :: Proxy (Void, Int -> Int)
Proxy

Proxy can even hold types of higher kinds,

>>> Proxy :: Proxy Either
Proxy

>>> Proxy :: Proxy Functor
Proxy

>>> Proxy :: Proxy complicatedStructure
Proxy

class f (g x) => Compose (f :: k -> Constraint) (g :: k1 -> k) (x :: k1) infixr 9 #

Composition of constraints.

Note that the result of the composition must be a constraint, and therefore, in Compose f g, the kind of f is k -> Constraint. The kind of g, however, is l -> k and can thus be a normal type constructor.

A typical use case is in connection with All on an NP or an NS. For example, in order to denote that all elements on an NP f xs satisfy Show, we can say All (Compose Show f) xs.
