### Attributes
#### `needs_input`
- **Type**: bool
- **Description**: If the `max_length` limit in `decompress` has been reached and the decompressor has unconsumed input, this is set to `False`. Passing `b''` to `decompress` may yield more data. It can be `True` even if all input is consumed.

#### `eof`
- **Type**: bool
- **Description**: `True` if the end of the first frame has been reached. Decompressing further will raise an `EOFError`. This can be `False` even if all input is consumed.

#### `unused_data`
- **Type**: bytes
- **Description**: Input data remaining after the end mark of the first frame. If no data remains after the end mark, this will be `b''`.

## Ppmd8Encoder

Encoder for PPMd Variant I version 2.

### Parameters

*   **max_order** (int) - The maximum order parameter, between 2 and 64.
*   **mem_size** (int) - The memory size in bytes that the encoder will use.
*   **restore_method** (int) - The restore method, which should be either ``PPMD8_RESTORE_METHOD_RESTART`` or ``PPMD8_RESTORE_METHOD_CUTOFF``.

### Methods

#### encode(data: Union[bytes, bytearray, memoryview]) -> bytes

Compresses the provided data and returns a bytes object containing the compressed data. This data should be appended to any output from previous calls. Some input may be retained in an internal buffer for future processing.

#### flush(endmark: bool = True) -> bytes

Processes all pending input and returns a bytes object with the remaining compressed output. After calling `flush()`, the `encode()` method cannot be used again.

## Ppmd8Decoder

Decoder for PPMd Variant I version 2.

### Parameters

*   **max_order** (int) - The maximum order parameter, between 2 and 64. This should match the encoder's setting.
*   **mem_size** (int) - The memory size in bytes used by the encoder. This should match the encoder's setting.
*   **restore_method** (int) - The restore method used by the encoder. This should match the encoder's setting.

### Methods

#### decode(data: Union[bytes, bytearray, memoryview], length: int = -1) -> bytes

Decodes the given data and returns the decoded data. If `length` is -1, the maximum possible output data is returned. If the decoder encounters the end mark, it automatically flushes all data and closes some resources. The `Ppmd8Decoder.eof` member becomes `True` when the end mark is reached. If `Ppmd8Decoder.needs_input` is `True`, all input data has been consumed, and more input is required to generate output. Otherwise, there is data in the internal buffer that can be reused. The decoder might return data smaller than the specified `length` if the input data is insufficient for full decoding.

*   **data** (Union[bytes, bytearray, memoryview]) - The compressed data to decode.
*   **length** (int) - The maximum amount of decoded data to return. If -1 (default), returns the maximum possible output data.
*   Returns decoded data. If the decoder reaches the end mark, `Ppmd8Decoder.eof` becomes True. If `Ppmd8Decoder.needs_input` is True, more input data is required. The decoder may return data smaller than `length` if input data is insufficient.
