The file handle may be for a non-seekable file, so it shouldn’t be ‘Sendable’, however, most of the work performed on behalf of the handle is executed in a thread pool which means that its state must be ‘Sendable’.
This declaration is gated by at least one @_spi attribute.
struct SendableViewimport _NIOFileSystemA file system library for Swift.
final class SystemFileHandleAn implementation of FileHandleProtocol which is backed by system calls and a file descriptor.
init(takingOwnershipOf descriptor: FileDescriptor, path: FilePath, materialization: Materialization? = nil, threadPool: NIOThreadPool) Creates a handle which takes ownership of the provided descriptor.
