我创建了以下结构

pub const BUCKET_SIZE: usize = 4;

pub const FINGERPRINT_SIZE: usize = 1;

pub struct Fingerprint ([u8; FINGERPRINT_SIZE]);

impl Fingerprint {
    pub fn new(bytes: [u8; FINGERPRINT_SIZE]) -> Fingerprint {
        return Fingerprint(bytes);
    }
}

pub struct Bucket ([Fingerprint; BUCKET_SIZE]);

impl Bucket {
    pub fn new(fingerprints: [Fingerprint; BUCKET_SIZE]) -> Bucket {
        Bucket(fingerprints)
    }
    pub fn insert(&self, fp: Fingerprint) -> bool {
        for i in 0..BUCKET_SIZE {



            //HERE IS THE ERROR
            if (self[i as usize] == 0) {
                self[i as usize] = fp; …
