hashLanes

[common]
fun hashLanes(input: Tensor, key: Long = 0, algo: HashLaneAlgo = HashLaneAlgo.AUTO, maskBits: Long = 0): Tensor

hashLanes(input: Tensor, key: Long = 0L, algo: HashLaneAlgo = HashLaneAlgo.AUTO, maskBits: Long = 0L): the hash_lanes operator. Elementwise per-lane BIJECTIVE hash, shape-preserving: every lane of an integer input maps through a permutation of its width, so distinct lane values stay distinct (a lane-wise content id, a bucket index, a deterministic shuffle key). A 32-bit lane lands as UInt32, a 64-bit lane as UInt64; algo selects the permutation within the input's width (HashLaneAlgo::Auto: Triple32 for 32-bit lanes, Moremur for 64-bit ones). key perturbs the permutation (0 is a fixed valid default, so the same key gives the same map on every platform and backend). mask_bits in (0, width] restricts the bijection to [0, 2^mask_bits): a lane below that bound maps to a lane below it, so a table of that size is permuted onto itself; 0 (and the lane width) keeps the full width.
