# AsyncThrowingDropWhileSequence

An asynchronous sequence which omits elements from the base sequence until a given error-throwing closure returns false, after which it passes through all remaining elements.

## Declaration

```swift
struct AsyncThrowingDropWhileSequence<Base> where Base : AsyncSequence
```
