# resume(with:)

Resume the task that’s awaiting the continuation by returning or throwing the given result value.

## Declaration

```swift
func resume(with result: sending Result<T, E>)
```

## Parameters

- `result`: The result. If it contains a .success value, the continuation returns that value; otherwise, it throws the .error value.

## Discussion

Discussion A continuation must be resumed exactly once. If the continuation has already resumed, then calling this method results in undefined behavior. After calling this method, control immediately returns to the caller. The task continues executing when its executor schedules it.
