rust - 大佬帮忙Go 语言并发读写代码的用Rust 实现？

Question

请大佬帮忙把一段之前golang实现的并发读写代码用rust实现

package mainimport (    "fmt"    "sync"    "time")type Rule struct {    Id    int64    Words []string}type Repo struct {    Version int64    rwLock  sync.RWMutex    Rules   []*Rule}func main() {    r0 := Rule{        Id:    0,        Words: []string{"a", "b", "c"},    }    r1 := Rule{        Id:    1,        Words: []string{"0", "1", "2"},    }    repo := Repo{        Version: 0,        Rules: []*Rule{            &r0,            &r1,        },    }    var wg sync.WaitGroup    wg.Add(2)    go func() {        repo.rwLock.RLock()        rs := repo.Rules        repo.rwLock.RUnlock()        time.Sleep(2 * time.Second)        for i := range rs {            fmt.Println(rs[i].Id)        }        wg.Done()    }()    go func() {        time.Sleep(1 * time.Second)        repo.rwLock.Lock()        repo.Rules[1].Id = 999        repo.Rules = repo.Rules[0:1]        repo.Rules[0].Id = 1000        repo.rwLock.Unlock()        wg.Done()    }()    wg.Wait()}

use std::sync::{Arc, Mutex};use std::thread;use std::time::Duration;struct Rule {    id: i64,    words: Vec<String>,}struct Repo {    version: i64,    rules: Vec<Arc<Mutex<Rule>>>,}fn main() {    let r0 = Arc::new(Mutex::new(Rule {        id: 0,        words: vec!["a".to_string(), "b".to_string(), "c".to_string()],    }));    let r1 = Arc::new(Mutex::new(Rule {        id: 1,        words: vec!["0".to_string(), "1".to_string(), "2".to_string()],    }));    let repo = Arc::new(Repo {        version: 0,        rules: vec![r0, r1],    });    let mut handles = Vec::new();    let repo_for_read = Arc::clone(&repo);    let handle1 = thread::spawn(move || {        let repo = repo_for_read;        let rs = repo.rules.clone();        thread::sleep(Duration::from_secs(2));        for r in rs.iter() {            println!("{}", r.lock().unwrap().id);        }    });    handles.push(handle1);    let repo_for_write = Arc::clone(&repo);    let handle2 = thread::spawn(move || {        thread::sleep(Duration::from_secs(1));        let mut rules = repo_for_write.rules.clone();        if let Some(r) = rules.get_mut(1) {            let mut r = r.lock().unwrap();            r.id = 999;        }        rules.remove(1);        if let Some(r) = rules.get_mut(0) {            let mut r = r.lock().unwrap();            r.id = 1000;        }    });    handles.push(handle2);    for handle in handles {        handle.join().unwrap();    }}
