Documentation
class HasBlueprintDefinition (t ∷ Type) where Source #
Designates a class of types that could be used as a Blueprint Definition.
Each such type:
- could be unrolled to a list of all nested types (including the type itself).
- has a unique DefinitionId.
Minimal complete definition
Nothing
Associated Types
type Unroll t ∷ [Type] Source #
type Unroll t = Insert t (GUnroll (IfStuckRep (RepIsStuckError t) (Rep t)))
Methods
definitionId ∷ DefinitionId Source #
default definitionId ∷ Typeable t ⇒ DefinitionId Source #
Instances
type family UnrollIsStuckError x where ... Source #
Compile-time error that happens when a type couldn't be unrolled
(Unroll TF is "stuck")
Equations
| UnrollIsStuckError x = TypeError (Text "No instance: " :<>: ShowType (HasBlueprintDefinition x)) |
type family RepIsStuckError x where ... Source #
Compile-time error that happens when type's generic representation is not defined
(Rep TF is "stuck")
type Unrolled t = Reverse (IfStuckUnroll (UnrollIsStuckError t) (Unroll t)) Source #
Same as Unroll but with a nicer error message
