def
firstIndexAndNumElementUnchecked(mask: ColumnView, indices: ColumnVector, numElements: ColumnVector): (Int, Int)
Return the first int value (should be valid) in 'indices' and 'numElements' as a pair where the corresponding row in 'mask' is true.
Return the first int value (should be valid) in 'indices' and 'numElements' as a pair where the corresponding row in 'mask' is true. Null rows in mask are skipped.
Both 'indices' and 'numElements' should be column of int, and have the same row number. 'mask' should be a boolean column, and have the same row number with 'indices'. Otherwise, the behavior is undefined.
This is made for outputting more details for invalid index error in GpuElementAt and GpuGetArrayItem. So the caller should take care of the limitations.
