Example of wrapper for RwLock that includes tracking of open lock-guards (for easy debugging of deadlocks)
use std::{sync::{Mutex, Arc}, ops::{Deref, DerefMut}};
use tokio::sync::{RwLock, RwLockReadGuard, RwLockWriteGuard};
/// Wrapper around RwLock, which:
/// 1) Requires that anyone who takes a lock-guard must supply their "name".
/// 2) Provides a way for anyone to get a list of "current lock-guard holders". (without having to take a lock-guard themselves)
pub struct RwLock_Tracked<T> {
l: RwLock<T>,
live_guards: Arc<Mutex<Vec<String>>>,

export const Parent = (props: {})=> {

return (
<div onClick={()=>childHandle.SayHi()}>
<Child name="Bob" ref={c=>childHandle = c}/>
