struct FileIOFileIO is a convenience wrapper around SwiftNIO’s NonBlockingFileIO.
@frozen struct StringA Unicode string value that is a collection of characters.
struct ByteBufferByteBuffer stores contiguously allocated raw bytes. It is a random and sequential accessible sequence of zero or more bytes (octets).
func asyncStreamFile(at path: String, chunkSize: Int = NonBlockingFileIO.defaultChunkSize, mediaType: HTTPMediaType? = nil, advancedETagComparison: Bool = false, onCompleted: @escaping (Result<Void, Error>) async throws -> () = { _ in }) async throws -> Response Generates a chunked Response for the specified file. This method respects values in the "ETag" header and is capable of responding 304 Not Modified if the file in question has not been modified since last served. If advancedETagComparison is set to true, the response will have its ETag field set to a byte-by-byte hash of the requested file. If set to false, a simple ETag consisting of the last modified date and file size will be used. This method will also set the "Content-Type" header automatically if an appropriate MediaType can be found for the file’s suffix.
func readFile(at path: String, chunkSize: Int = NonBlockingFileIO.defaultChunkSize, offset: Int64? = nil, byteCount: Int? = nil) async throws -> FileChunks Reads the contents of a file at the supplied path in chunks.

func writeFile(_ buffer: ByteBuffer, at path: String) async throws Write the contents of buffer to a file at the supplied path.
struct FileChunksWrapper around NIOFileSystem.FileChunks. This can be removed once NIOFileSystem reaches a stable API.
func collectFile(at path: String) -> EventLoopFuture<ByteBuffer> Reads the contents of a file at the supplied path.
