| ErrorDeclaration :: !DeclarationException -> Error | Agda declaration exception. |
| ErrorFile :: !(Maybe Range) -> !QName -> !FilePath -> Error | File not found. |
| ErrorFixity :: !(Maybe Range) -> Error | Agda fixity exception. |
| ErrorInternal :: !InternalError -> !Range -> Error | Internal error; should be reported. |

data InternalError where Source #
An internal error, indicating a bug in our code. This type of error should be reported by filing an issue.
Constructors
| ErrorConstructor :: InternalError | Unexpected declaration type for constructor. |
| ErrorMacro :: InternalError | Unexpected arguments to SectionApp constructor. |
| ErrorName :: InternalError | Unexpected underscore as name. |
| ErrorRenaming :: InternalError | Unexpected name-module mismatch in renaming statement. |
| ErrorUnexpected :: !UnexpectedError -> InternalError | Unexpected data type constructor. |
