Various errors that might happen during type checking/inference
Constructors
| KindMismatch (Maybe TypeSource) Kind Kind | Expected kind, inferred kind |
| TooManyTypeParams Int Kind | Number of extra parameters, kind of result
(which should not be of the form |
| TyVarWithParams | A type variable was applied to some arguments. |
| TooManyTySynParams Name Int | Type-synonym, number of extra params |
| TooFewTyParams Name Int | Who is missing params, number of missing params |
| RecursiveTypeDecls [Name] | The type synonym declarations are recursive |
| TypeMismatch TypeSource Type Type | Expected type, inferred type |
| RecursiveType TypeSource Type Type | Unification results in a recursive type |
| UnsolvedGoals [Goal] | A constraint that we could not solve, usually because there are some left-over variables that we could not infer. |
| UnsolvableGoals [Goal] | A constraint that we could not solve and we know it is impossible to do it. |
| UnsolvedDelayedCt DelayedCt | A constraint (with context) that we could not solve |
| UnexpectedTypeWildCard | Type wild cards are not allowed in this context (e.g., definitions of type synonyms). |
| TypeVariableEscaped TypeSource Type [TParam] | Unification variable depends on quantified variables that are not in scope. |
| NotForAll TypeSource TVar Type | Quantified type variables (of kind *) need to match the given type, so it does not work for all types. |
| TooManyPositionalTypeParams | Too many positional type arguments, in an explicit type instantiation |
| CannotMixPositionalAndNamedTypeParams | |
| UndefinedTypeParameter (Located Ident) | |
| RepeatedTypeParameter Ident [Range] | |
| AmbiguousSize TVarInfo (Maybe Type) | Could not determine the value of a numeric type variable, but we know it must be at least as large as the given type (or unconstrained, if Nothing). |
| UndefinedExistVar Name | |
| TypeShadowing String Name String | |
| MissingModTParam (Located Ident) | |
| MissingModVParam (Located Ident) |
