This is used for generating various names.
Various errors that might happen during type checking/inference
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 |
TooManyTySynParams Name Int | Type-synonym, number of extra params |
TooFewTySynParams Name Int | Type-synonym, number of missing params |
RepeatedTyParams [TParam Name] | Type parameters with the same name (in definition) |
RepeatedDefinitions Name [Range] | Multiple definitions for the same name |
RecursiveTypeDecls [Name] | The type synonym declarations are recursive |
UndefinedTypeSynonym Name | Use of a type synonym that was not defined |
UndefinedVariable Name | Use of a variable that was not defined |
UndefinedTypeParam (Located Ident) | Attempt to explicitly instantiate a non-existent param. |
MultipleTypeParamDefs Ident [Range] | Multiple definitions for the same type parameter |
TypeMismatch Type Type | Expected type, inferred type |
RecursiveType Type Type | Unification results in a recursive type |
UnsolvedGoal 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 [TVar] | 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. |
UnusableFunction Name [Prop] | The given constraints causes the signature of the function to be not-satisfiable. |
TooManyPositionalTypeParams | Too many positional type arguments, in an explicit type instantiation |
CannotMixPositionalAndNamedTypeParams | |
AmbiguousType [Name] |
