Struct QuantizePerTensorBackwardDescriptor 

pub struct QuantizePerTensorBackwardDescriptor {
    pub numel: i32,
    pub q_min: i32,
    pub q_max: i32,
    pub input_element: ElementKind,
    pub output_element: ElementKind,
}

Descriptor for a quantize_per_tensor backward op. Mirrors the FW descriptor with numel / q_min / q_max. The output dtype field records which int output the FW targeted (needed to keep the kernel SKU’s aux_element consistent between FW and BW) — though the BW itself produces an FP gradient.

Fields

numel: i32

Total element count.

q_min: i32

Lower clip bound from FW.

q_max: i32

Upper clip bound from FW.

input_element: ElementKind

Input FP element kind.

output_element: ElementKind

FW’s output int element kind (s8 or u8). Recorded for SKU consistency; the BW kernel itself doesn’t consume it.
