Very simple type-safe addListener, removeListener, trigger - basically Event / EventEmitter implementation with typesafety
export function simpleMapEvent<TParam, TRes = void, TContext = unknown>(context?: TContext) {
type T = { (this: TContext, inputs: TParam): TRes };
return {
cbs: [] as [T, T][], // First value is used for equality check, second is the bound version
addListener(cb: T, bindThis?: unknown) {
return this.cbs.push([cb, bindThis ? cb.bind(bindThis as TContext) : cb]);
},
removeListener(cb: T) {
const i = this.cbs.findIndex(([v, _]) => v == cb);
if (i >= 0) return this.cbs.splice(i, 1);

Why this panics? "fatal runtime error: thread local panicked on drop"
struct MyThreadWrapper {
thread: Option<std::thread::JoinHandle<()>>,
}
impl Drop for MyThreadWrapper {
fn drop(&mut self) {
if let Some(thread) = self.thread.take() {
