data Error Source #

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)

errorImportance :: Error -> Int Source #

When we have multiple errors on the same location, we show only the ones with the has highest rating according to this function.

computeFreeVarNames :: [(Range, Warning)] -> [(Range, Error)] -> NameMap Source #

This picks the names to use when showing errors and warnings.
