return result, pos - offset

While implementing LEB128 from scratch can be a valuable learning experience, you may also want to consider using existing libraries that provide LEB128 support, such as varint . These libraries can save you time and effort while providing an efficient and reliable implementation of LEB128 encoding. leb128 python

Signed encoding uses two’s complement logic to handle negative numbers. Returns (value, bytes_consumed)
