Expand description

Error information for when the program we executed turned out not to actually be a valid program. This cannot happen in stand-alone Miri, but it can happen during CTFE/ConstProp where we work on generic code or execution does not have all information available.

Variants

`TooGeneric`

Resolution can fail if we are in a too generic context.

`ReferencedConstant`

Cannot compute this constant because it depends on another one which already produced an error.

`AlreadyReported(ErrorGuaranteed)`

Abort in case errors are already reported.

`Layout(LayoutError<'tcx>)`

An error occurred during layout computation.

`FnAbiAdjustForForeignAbi(AdjustForForeignAbiError)`

An error occurred during FnAbi computation: the passed –target lacks FFI support (which unfortunately typeck does not reject). Not using FnAbiError as that contains a nested LayoutError.

`SizeOfUnsizedType(Ty<'tcx>)`

SizeOf of unsized type was requested.
