You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: lib.rs
    path of file: ./repos/enigma-core/examples/eng_wasm_contracts/factorization/src
    
    the code of the file until where you have to start completion: #![no_std]

use eng_wasm_derive::pub_interface;

struct S;

#[pub_interface]
impl S {
    pub fn find_number_of_prime_factors(mut number: u64) -> u64{
        if number == 0 {return 0;}
        // The maximal number of 2s that divide `number`
        let mut result = number.trailing_zeros() as u64;
        let factor_bound = ((number as f64).sqrt().ceil()) as u64;

        number >>= result;

        for i in (3..=factor
    
    pub fn find_number_of_prime_factors(mut number: u64) -> u64{
        if number == 0 {return 0;}
        // The maximal number of 2s that divide `number`
        let mut result = number.trailing_zeros() as u64;
        let factor_bound = ((number as f64).sqrt().ceil()) as u64;

        number >>= result;

        for i in (3..=factor_bound).step_by(2) {
            while number % i == 0 {
                result += 1;
                number = number / i;
            }
        }
        if number > 1 {
            result += 1;
