    This is a simplified flate compression algorithm based on Go's implementation: https://cs.opensource.google/go/go/+/refs/tags/go1.23.1:src/compress/flate/deflatefast.go which has the copyright notice:

    Reader

    source
    pub(open) trait Reader {
      fn read(Self, 
    Slice    [Byte]) -> (Int, 
    IOError    ?)
      fn read_byte(Self) -> (Byte, 
    IOError    ?)
    }

    The actual read interface needed by [Decompressor::new].
    impl Reader for Buffer

    Decompressor

    source
    type Decompressor

    Decompressor::make_reader

    source
    fn Decompressor::make_reader(self : Decompressor, r : &Reader) -> Unit

    Decompressor::reset

    source
    fn Decompressor::reset(self : Decompressor, r : &Reader, dict : 
    Slice    [Byte]) -> Unit

    DictWriter

    source
    type DictWriter

    Writer

    source
    type Writer

    impl Closer for Writer
    impl Writer for Writer

    Writer::new

    source

    Writer::new returns a new [@io.WriteCloser] compressing data at the "BestSpeed" level. It writes its (compressed) data to the provided buf.

    Writer::new_dict

    source
    fn Writer::new_dict(w : &
    Writer    , dict : 
    Slice    [Byte]) -> Writer

    ioeof

    source

    writer_closed_error

    source
    let writer_closed_error : 
    IOError
