44 /** Error codes returned by the codec.
48 /** Additional buffers are required.
50 This error indicates that one or both of the buffers
51 provided buffers do not have sufficient available bytes
52 to make forward progress.
54 This does not always indicate a failure condition.
56 @note This is the same as `Z_BUF_ERROR` returned by ZLib.
60 /** End of stream reached.
62 @note This is the same as `Z_STREAM_END` returned by ZLib.
66 /** Invalid stream or parameters.
68 This error is returned when invalid parameters are passed,
69 or the operation being performed is not consistent with the
70 state of the stream. For example, attempting to write data
71 when the end of stream is already reached.
73 @note This is the same as `Z_STREAM_ERROR` returned by ZLib.
