struct AsyncPrefixWhileSequence<Base> where Base : AsyncSequenceAn asynchronous sequence, containing the initial, consecutive elements of the base sequence that satisfy a given predicate.
associatedtype Failure = any Error where Self.Failure == Self.AsyncIterator.FailureThe type of errors produced when iteration over the sequence fails.
mutating func next() async rethrows -> Base.Element? Produces the next element in the prefix-while sequence.
mutating func next(isolation actor: isolated (any Actor)?) async throws(AsyncPrefixWhileSequence<Base>.Iterator.Failure) -> Base.Element? Produces the next element in the prefix-while sequence.
