Summary
ZeroCodecgains a keywordvalue: int | float = 0and decodes tonp.full(shape, value, dtype). The default behaviour (all zeros) and the stream format are unchanged;get_configand__repr__are added so that the value round-trips through the configuration.Motivation
Some safety requirements in the compression recommendations are so loose that a constant reconstruction (e.g. the field's median) satisfies them; combined with
MaskMetaCodecfor missing values this gives the smallest possible representation without a dedicated "constant" codec.
