Data.Singletons.Base.TypeError

Description

Defines a drop-in replacement for TypeError (from GHC.TypeLits) that can be used at the value level as well. Since this is a drop-in replacement, it is not recommended to import all of GHC.TypeLits and Data.Singletons.Base.TypeError at the same time, as many of the definitions in the latter deliberately clash with the former.

Documentation

type family TypeError (x :: PErrorMessage) :: a where ... Source #

A drop-in replacement for TypeError. This also exists at the value-level as typeError.

Equations

TypeError x = TypeError (ConvertPErrorMessage x)

sTypeError :: HasCallStack => Sing err -> Sing (TypeError err) Source #

The singleton for typeError.

Note that this is not quite as expressive as TypeError, as it is unable to handle ShowType constructors at all.

typeError :: HasCallStack => ErrorMessage -> a Source #

The value-level counterpart to TypeError.

Note that this is not quite as expressive as TypeError, as it is unable to print the contents of ShowType constructors (it will simply print "<type>" in their place).

data ErrorMessage' s Source #

A description of a custom type error.

This is a variation on ErrorMessage that is parameterized over what text type is used in the Text constructor. Instantiating it with Text gives you ErrorMessage, and instantiating it with Symbol gives you PErrorMessage.

Constructors

Text s	Show the text as is.
forall t. ShowType t	Pretty print the type. `ShowType :: k -> ErrorMessage`
(ErrorMessage' s) :<>: (ErrorMessage' s) infixl 6	Put two pieces of error message next to each other.
(ErrorMessage' s) :$$: (ErrorMessage' s) infixl 5	Stack two pieces of error message on top of each other.

type Sing Source #	A choice of singleton for the kind `TYPE rep` (for some `RuntimeRep` `rep`), an instantiation of which is the famous kind `Type`. Conceivably, one could generalize this instance to `Sing @k` for any kind `k`, and remove all other `Sing` instances. We don't adopt this design, however, since it is far more convenient in practice to work with explicit singleton values than `TypeRep`s (for instance, `TypeRep`s are more difficult to pattern match on, and require extra runtime checks). We cannot produce explicit singleton values for everything in `TYPE rep`, however, since it is an open kind, so we reach for `TypeRep` in this one particular case.
