Crate sim_lib_numbers_tensor_bit 

Bit-tensor specialization: a packed-word boolean tensor element type and its SpecTensor backend, with bitwise operations over the tensor domain.

BitTensor is the storage type (booleans packed into u64 words) with element-wise bit_and, bit_or, and bit_xor. BitTensorLib registers it as the bool element-type backend for the base tensor domain.

Examples

Pack booleans, combine two tensors bit-for-bit, and unpack the result:

use sim_lib_numbers_tensor_bit::BitTensor;

let left = BitTensor::from_bools(vec![4], &[true, false, true, true]).unwrap();
let right = BitTensor::from_bools(vec![4], &[true, true, false, true]).unwrap();
let masked = left.bit_and(&right).unwrap();
assert_eq!(masked.to_bools(), vec![true, false, false, true]);

Shape mismatches fail closed rather than truncate:

use sim_lib_numbers_tensor_bit::BitTensor;

let a = BitTensor::from_bools(vec![2], &[true, false]).unwrap();
let b = BitTensor::from_bools(vec![3], &[true, false, true]).unwrap();
assert!(a.bit_or(&b).is_none());
