func allSatisfy((Self.Element) async throws -> Bool) async rethrows -> Bool Returns a Boolean value that indicates whether all elements produced by the asynchronous sequence satisfy the given predicate.
func compactMap<ElementOfResult>(@escaping (Self.Element) async -> ElementOfResult?) -> AsyncCompactMapSequence<Self, ElementOfResult> Creates an asynchronous sequence that maps the given closure over the asynchronous sequence’s elements, omitting results that don’t return a value.
func compactMap<ElementOfResult>(@escaping (Self.Element) async throws -> ElementOfResult?) -> AsyncThrowingCompactMapSequence<Self, ElementOfResult> Creates an asynchronous sequence that maps an error-throwing closure over the base sequence’s elements, omitting results that don’t return a value.
func contains(Self.Element) async rethrows -> Bool Returns a Boolean value that indicates whether the asynchronous sequence contains the given element.
func contains(where: (Self.Element) async throws -> Bool) async rethrows -> Bool Returns a Boolean value that indicates whether the asynchronous sequence contains an element that satisfies the given predicate.
func drop(while: @escaping (Self.Element) async -> Bool) -> AsyncDropWhileSequence<Self> Omits elements from the base asynchronous sequence until a given closure returns false, after which it passes through all remaining elements.
func dropFirst(Int) -> AsyncDropFirstSequence<Self> Omits a specified number of elements from the base asynchronous sequence, then passes through all remaining elements.
func filter(@escaping (Self.Element) async -> Bool) -> AsyncFilterSequence<Self> Creates an asynchronous sequence that contains, in order, the elements of the base sequence that satisfy the given predicate.
