Width is the amount of bits to generate. If width is larger than the actual amount of bits required to represent number in binary, sign-extension is used. If it's smaller, the representation is trimmed to width bits. Each bit is represented as either \\x00 or \\x01. The most significant is first, big-endian. This is reverse to `bits2integer`. Examples: >>> integer2bits(19, 8) b'\x00\x00\x00\x01\x00\x00\x01\x01' rwidth must be non-negative ValueErrorintint2bytejoin)numberwidthbitsirF/var/www/html/env/lib/python3.10/site-packages/construct/lib/binary.py integer2bitss     rcCs||dkrtdt|}|dkr|d|d>7}dg|}|d}|dkr9t|d@||<|dL}|d8}|dks%d|S)z Converts a bytes-string into an integer.
