Mu.Schema.Interpretation

Description

This module defines Terms which comply with a given Schema. These Terms are the main form of values used internally by mu-haskell.

This module follows the ideas of higher-kinded data. In particular, each interpretation of a Field wraps its contents into a "wrapper" type w, which may add additional behavior to it. For example, in Protocol Buffers every field is optional, and this is expressed by setting w to Maybe.

In this module we make use of NP and NS as defined by sop-core. These are the n-ary versions of a pair and Either, respectively. In other words, NP puts together a bunch of values of different types, NS allows you to choose from a bunch of types.

Synopsis

data NS (a :: k -> Type) (b :: [k]) where #

An n-ary sum.

The sum is parameterized by a type constructor f and indexed by a type-level list xs. The length of the list determines the number of choices in the sum and if the i-th element of the list is of type x, then the i-th choice of the sum is of type f x.

The constructor names are chosen to resemble Peano-style natural numbers, i.e., Z is for "zero", and S is for "successor". Chaining S and Z chooses the corresponding component of the sum.

Examples:

Z         :: f x -> NS f (x ': xs)
S . Z     :: f y -> NS f (x ': y ': xs)
S . S . Z :: f z -> NS f (x ': y ': z ': xs)
...

Note that empty sums (indexed by an empty list) have no non-bottom elements.

Two common instantiations of f are the identity functor I and the constant functor K. For I, the sum becomes a direct generalization of the Either type to arbitrarily many choices. For K a, the result is a homogeneous choice type, where the contents of the type-level list are ignored, but its length specifies the number of options.

In the context of the SOP approach to generic programming, an n-ary sum describes the top-level structure of a datatype, which is a choice between all of its constructors.

Examples:

Z (I 'x')      :: NS I       '[ Char, Bool ]
S (Z (I True)) :: NS I       '[ Char, Bool ]
S (Z (K 1))    :: NS (K Int) '[ Char, Bool ]

Constructors

Z :: forall k (a :: k -> Type) (x :: k) (xs :: [k]). a x -> NS a (x ': xs) 
S :: forall k (a :: k -> Type) (xs :: [k]) (x :: k). NS a xs -> NS a (x ': xs)

data NP (a :: k -> Type) (b :: [k]) where #

An n-ary product.

The product is parameterized by a type constructor f and indexed by a type-level list xs. The length of the list determines the number of elements in the product, and if the i-th element of the list is of type x, then the i-th element of the product is of type f x.

The constructor names are chosen to resemble the names of the list constructors.

Two common instantiations of f are the identity functor I and the constant functor K. For I, the product becomes a heterogeneous list, where the type-level list describes the types of its components. For K a, the product becomes a homogeneous list, where the contents of the type-level list are ignored, but its length still specifies the number of elements.

In the context of the SOP approach to generic programming, an n-ary product describes the structure of the arguments of a single data constructor.

Examples:

I 'x'    :* I True  :* Nil  ::  NP I       '[ Char, Bool ]
K 0      :* K 1     :* Nil  ::  NP (K Int) '[ Char, Bool ]
Just 'x' :* Nothing :* Nil  ::  NP Maybe   '[ Char, Bool ]

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

Change the underlying wrapper of a term.

transWrapNoMaps :: forall tn fn (sch :: Schema tn fn) t u v. Functor u => (forall a. u a -> v a) -> Term u sch t -> Term v sch t Source #

Change the underlying wrapper of a term. This version assumes that no field is a map, which allows for a more general type. If a map is found, an exception is raised.

For internal use only

transFields :: forall tn fn (sch :: Schema tn fn) args u v. (Functor u, forall k. Ord (FieldValue u sch k) => Ord (FieldValue v sch k)) => (forall a. u a -> v a) -> NP (Field u sch) args -> NP (Field v sch) args Source #

transFieldsNoMaps :: forall tn fn (sch :: Schema tn fn) args u v. Functor u => (forall a. u a -> v a) -> NP (Field u sch) args -> NP (Field v sch) args Source #

Change the underlying wrapper of a list of fields. This version assumes no maps are present as fields.

transValue :: forall tn fn (sch :: Schema tn fn) l u v. (Functor u, forall k. Ord (FieldValue u sch k) => Ord (FieldValue v sch k)) => (forall a. u a -> v a) -> FieldValue u sch l -> FieldValue v sch l Source #

Change the underlying wrapper of a value.

transValueNoMaps :: forall tn fn (sch :: Schema tn fn) l u v. Functor u => (forall a. u a -> v a) -> FieldValue u sch l -> FieldValue v sch l Source #

Change the underlying wrapper of a value. This version assumes that the value is not a map.
