method AsyncLocalStorage.prototype.run
Usage in Deno
```typescript import { AsyncLocalStorage } from "node:node__async_hooks.d.ts"; ```
AsyncLocalStorage.prototype.run<R>(store: T,callback: () => R,): R
Runs a function synchronously within a context and returns its
return value. The store is not accessible outside of the callback function.
The store is accessible to any asynchronous operations created within the
callback.
The optional `args` are passed to the callback function.
If the callback function throws an error, the error is thrown by `run()` too.
The stacktrace is not impacted by this call and the context is exited.
Example:
```js
const store = { id: 2 };
try {
asyncLocalStorage.run(store, () => {
asyncLocalStorage.getStore(); // Returns the store object
setTimeout(() => {
asyncLocalStorage.getStore(); // Returns the store object
}, 200);
throw new Error();
});
} catch (e) {
asyncLocalStorage.getStore(); // Returns undefined
// The error will be caught here
}
```
callback: () => R
