Functions

func GzipReader

func GzipReader(r io.Reader) (io.Reader, error)

func NewFile

func NewFile(zctx *zed.Context, rc io.ReadCloser, path string, demandOut demand.Demand, opts ReaderOpts) (*zbuf.File, error)

func NewReader

func NewReader(zctx *zed.Context, r io.Reader, demandOut demand.Demand) (zio.ReadCloser, error)

func NewReaderWithOpts

func NewReaderWithOpts(zctx *zed.Context, r io.Reader, demandOut demand.Demand, opts ReaderOpts) (zio.ReadCloser, error)

func NewWriter

func NewWriter(w io.WriteCloser, opts WriterOpts) (zio.WriteCloser, error)

func Open

func Open(ctx context.Context, zctx *zed.Context, engine storage.Engine, path string, demandOut demand.Demand, opts ReaderOpts) (*zbuf.File, error)

Open uses engine to open path for reading. path is a local file path or a URI whose scheme is understood by engine.
