resultAsync: ResultAsync<T, E>,
fallbackFn: (err: E) => T,
) => Promise<T> = unwrapAsyncOrElse

See unwrapAsyncOrElse.

Type declaration

- <T, E extends unknown = Error>(
  resultAsync: ResultAsync<T, E>,
  fallbackFn: (err: E) => T,
  ): Promise<T>
- Unwraps a ResultAsync, computing a fallback value from the error when needed.
  Type Parameters
  - T
    The type of the value.
  - E extends unknown = Error
    The type of the error.
  Parameters
  - resultAsync: ResultAsync<T, E>
    The ResultAsync to unwrap.
  - fallbackFn: (err: E) => T
    A function that receives the error and returns a fallback value.
  Returns Promise<T>
  A promise that resolves to the unwrapped value or the computed fallback.
  Example
```
const value = await unwrapAsyncOrElse(Promise.resolve(ok(42)), () => 0);
console.log(value); // 42
```
  Example
```
const value = await unwrapAsyncOrElse(
  Promise.resolve(err(new Error("Oops"))),
  (error) => error.message.length,
);
console.log(value); // 4
