Function visual_hash_code

pub fn visual_hash_code(key: &str) -> u32

Calculates a bit-shifted hash code; The function initializes a 32-bit hash code integer to 0, then loops over each character in the input string; Each loop adds the next character in the string to the hash code as an integer value with wrapping; This ensures consistency across architectures; The next operation in each loop performs a cyclic bit shift on the hash code, and the process repeats
