type WithSingleDomain dom r = (HasSingleDomain r, dom ~ GetDomain r) Source #

Type that forces dom to be the same in all subtypes of r that might contain a domain. If given a polymorphic domain not tied to r, GHC will be allowed to infer that that domain is equal to the one in r on the condition that r contains just a single domain.

type family Merge' (n :: TryDomainResult) (m :: TryDomainResult) :: TryDomainResult where ... Source #

Type family to resolve type conflicts (if any)

Equations

Merge' 'NotFound b = b 
Merge' ('Ambiguous dom1 dom2) b = 'Ambiguous dom1 dom2 
Merge' a 'NotFound = a 
Merge' a ('Ambiguous dom1 dom2) = 'Ambiguous dom1 dom2 
Merge' ('Found dom) ('Found dom) = 'Found dom 
Merge' ('Found dom1) ('Found dom2) = 'Ambiguous dom1 dom2 

type family Merge (orig :: Type) (n :: Type) (m :: Type) :: TryDomainResult where ... Source #

Same as Merge', but will insert a type error if Merge' got stuck.

Equations

Merge orig n m = IfStuck (TryDomain orig n) (DelayError (StuckErrorMsg orig n)) (Pure (IfStuck (TryDomain orig m) (DelayError (StuckErrorMsg orig m)) (Pure (Merge' (TryDomain orig n) (TryDomain orig m))))) 

type family ErrOnConflict (t :: Type) (n :: TryDomainResult) :: Domain where ... Source #

Equations

ErrOnConflict t 'NotFound = TypeError (NotFoundError t) 
ErrOnConflict t ('Ambiguous dom1 dom2) = TypeError (AmbiguousError t dom1 dom2) 
ErrOnConflict t ('Found dom) = dom

class HasSingleDomain (r :: Type) Source #

Type family that searches a type and checks whether all subtypes that can contain a domain (for example, Signal) contain the same domain. Its associated type, GetDomain, will yield a type error if that doesn't hold OR if it can't check it.
