struct WriteFileHandleImplements WritableFileHandleProtocol by making system calls to interact with the local file system.
struct WriteFileHandleimport _NIOFileSystemA file system library for Swift.
protocol WritableFileHandleProtocol : FileHandleProtocolA file handle suitable for writing.
struct FileSystemA file system which interacts with the local system. The file system uses a thread pool to perform system calls.
struct FileHandleImplements FileHandleProtocol by making system calls to interact with the local file system.
protocol FileHandleProtocolA handle for a file system object.
struct ReadFileHandleImplements ReadableFileHandleProtocol by making system calls to interact with the local file system.
struct ReadWriteFileHandleImplements ReadableAndWritableFileHandleProtocol by making system calls to interact with the local file system.
struct DirectoryFileHandleImplements DirectoryFileHandleProtocol by making system calls to interact with the local file system.
func withFileSystem<Result>(numberOfThreads: Int, _ body: (FileSystem) async throws -> Result) async throws -> Result Provides temporary scoped access to a FileSystem with the given number of threads.
protocol _HasFileHandle : FileHandleProtocolProvides a FileHandle.
