Function retryable

Marks Durable Object methods as safe to run more than once. The runtime may then retry calls to them after a disconnect that might have happened after the method started. It does not enable retries or change how many are made.

Mark methods on the class prototype, for example from a static block:

class Counter extends DurableObject {
  static {
    retryable(this.prototype.reset);
  }
  async reset() {}
}
Copy

The mark is on the function itself. A subclass inherits it, but an override, a bound copy, or a wrapper is not marked unless it is also passed to retryable().

Each attempt creates its own return value, so if the method returns an RpcTarget, its [Symbol.dispose]() may run once per attempt.
