Instances
Various errors that might happen during type checking/inference
Constructors
| ErrorMsg Doc | Just say this |
| KindMismatch 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 |
| TooFewTySynParams Name Int | Type-synonym, number of missing params |
| RecursiveTypeDecls [Name] | The type synonym declarations are recursive |
| TypeMismatch Type Type | Expected type, inferred type |
| RecursiveType Type Type | Unification results in a recursive type |
| UnsolvedGoals Bool [Goal] | A constraint that we could not solve The boolean indicates if we know that this constraint is impossible. |
| 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 Type [TParam] | Unification variable depends on quantified variables that are not in scope. |
| NotForAll 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] |
