Encapsulates the ways converting from a VARIANT can fail.

Variants

VarTypeDoesNotMatch

Expected vartype did not match found vartype - runtime consistency check

Fields of VarTypeDoesNotMatch

expected: u32	The expected vartype
found: u32	the found vartype

AllocBStr(BStringError)

Encapsulates BString errors

UnknownPtrNull

IUnknown pointer during conversion was null

DispatchPtrNull

IDispatch pointer during conversion was null

VariantPtrNull

VARIANT pointer during conversion was null

ArrayPtrNull

SAFEARRAY pointer during conversion was null

CVoidPtrNull

*mut c_void pointer during conversion was null

SafeArrConvFailed(Box<SafeArrayError>)

Conversion into SAFEARRAY failed.
