Class MessageProcessor<Msg, HandlerOpts>

Wraps a MaybePromise-yielding coroutine (generator function) into a function that returns MaybePromise. This allows you to use maybeAsync/yield in a similar way to async/await, where yield maybePromise will return awaited / resolved value.

Example

const add = maybeAsync(function* (a: number, b: number) {
  const result1: number = yield Promise.resolve(a); // result1 === a
  const result2 = yield b; // result2 === b
  return result + result2;
});
const result = await add(1, 2); // result === 3
