Constructors
errorCode :: ErrorMessage -> String Source
Get the error code for a particular error type
nonEmpty :: MultipleErrors -> Bool Source
Check whether a collection of errors is empty or not.
errorMessage :: SimpleErrorMessage -> MultipleErrors Source
Create an error set from a single simple error message
singleError :: ErrorMessage -> MultipleErrors Source
Create an error set from a single error message
onErrorMessages :: (ErrorMessage -> ErrorMessage) -> MultipleErrors -> MultipleErrors Source
Lift a function on ErrorMessage to a function on MultipleErrors
The various types of things which might need to be relabelled in errors messages.

type UnknownMap = Map (LabelType, Unknown) Unknown Source
A map from rigid type variable name/unknown variable pairs to new variables.
unwrapErrorMessage :: ErrorMessage -> SimpleErrorMessage Source
Extract nested error messages from wrapper errors
replaceUnknowns :: Type -> State UnknownMap Type Source
onTypesInErrorMessageM :: Applicative m => (Type -> m Type) -> ErrorMessage -> m ErrorMessage Source
prettyPrintSingleError :: Bool -> ErrorMessage -> State UnknownMap Box Source
Pretty print a single error, simplifying if necessary
prettyPrintMultipleErrors :: Bool -> MultipleErrors -> String Source
Pretty print multiple errors
prettyPrintMultipleWarnings :: Bool -> MultipleErrors -> String Source
Pretty print multiple warnings
prettyPrintMultipleErrorsWith :: String -> String -> Bool -> MultipleErrors -> State UnknownMap String Source
interpretMultipleErrorsAndWarnings :: (MonadError MultipleErrors m, MonadWriter MultipleErrors m) => (Either MultipleErrors a, MultipleErrors) -> m a Source
Interpret multiple errors and warnings in a monad supporting errors and warnings
rethrow :: MonadError e m => (e -> e) -> m a -> m a Source
Rethrow an error with a more detailed error message in the case of failure
rethrowWithPosition :: MonadError MultipleErrors m => SourceSpan -> m a -> m a Source
Rethrow an error with source position information
parU :: (MonadError MultipleErrors m, Functor m) => [a] -> (a -> m b) -> m [b] Source
Collect errors in in parallel
