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: mod.rs
    path of file: ./repos/CaptfEncoder/CaptfEncoder-V3/encoding/src/converter/internal/uuencode
    
    the code of the file until where you have to start completion: // https://github.com/murtyjones/uuencode

pub fn uuencode(input: &[u8]) -> String {
    let mut output: Vec<u8> = Vec::new();
    for line in input.chunks(45) {
        let line_length = line.len() as u8 +
    
fn uudecode_chunk(input: &[u8]) -> impl Iterator<Item = u8> {
    let combined: u32 = input.iter().enumerate().fold(0, |acc, (index, &val)| {
        acc + (((val as u32) - 32) << 6 * (3 - index))
    });

    (0..3).rev().map(move |val| {
        let val = (combined >> (8 * val)) & 255;
        val as u8
    })
}
