Type Alias MlirPDLConstraintFunction 

pub type MlirPDLConstraintFunction = Option<unsafe extern "C" fn(rewriter: MlirPatternRewriter, results: MlirPDLResultList, nValues: usize, values: *mut MlirPDLValue, userData: *mut c_void) -> MlirLogicalResult>;

This function type is used as callbacks for PDL native constraint functions. Input values can be accessed by values with its size nValues; output values can be added into results by mlirPDLResultListPushBack* APIs. And the return value indicates whether the constraint holds.
