struct DirectoryEntriesAn AsyncSequence of entries in a directory.
struct DirectoryEntriesimport _NIOFileSystemA file system library for Swift.
struct DirectoryEntryInformation about an item within a directory.
protocol AsyncSequence<Element, Failure>A type that provides asynchronous, sequential, iterated access to its elements.
protocol Sendable@preconcurrency init<S>(wrapping sequence: S) where S : Sendable, S : AsyncSequence, S.Element == [DirectoryEntry] Creates a DirectoryEntries sequence by wrapping an AsyncSequence of batches of directory entries.
func batched() -> Batched Returns a sequence of directory entry batches.
func makeAsyncIterator() -> DirectoryIterator struct BatchedAn AsyncSequence of batches of directory entries.
struct DirectoryIteratorAn AsyncIteratorProtocol of DirectoryEntry.
typealias AsyncIterator = DirectoryIteratortypealias Element = DirectoryEntryfunc allSatisfy(_ predicate: (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.
@preconcurrency func compactMap<ElementOfResult>(_ transform: @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.
@preconcurrency func compactMap<ElementOfResult>(_ transform: @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(_ search: Self.Element) async rethrows -> Bool Returns a Boolean value that indicates whether the asynchronous sequence contains the given element.
func contains(where predicate: (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.
@preconcurrency func drop(while predicate: @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(_ count: Int = 1) -> AsyncDropFirstSequence<Self> Omits a specified number of elements from the base asynchronous sequence, then passes through all remaining elements.
@preconcurrency func filter(_ isIncluded: @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.
func first(where predicate: (Self.Element) async throws -> Bool) async rethrows -> Self.Element? Returns the first element of the sequence that satisfies the given predicate.
@preconcurrency func flatMap<SegmentOfResult>(_ transform: @escaping (Self.Element) async throws -> SegmentOfResult) -> AsyncThrowingFlatMapSequence<Self, SegmentOfResult> where SegmentOfResult : AsyncSequence Creates an asynchronous sequence that concatenates the results of calling the given error-throwing transformation with each element of this sequence.
@preconcurrency func flatMap<SegmentOfResult>(_ transform: @escaping (Self.Element) async -> SegmentOfResult) -> AsyncFlatMapSequence<Self, SegmentOfResult> where SegmentOfResult : AsyncSequence, Self.Failure == SegmentOfResult.Failure Creates an asynchronous sequence that concatenates the results of calling the given transformation with each element of this sequence.
