Expand description
Zarr codecs.
Array chunks can be encoded using a sequence of codecs, each of which specifies
a bidirectional transform (an encode transform and a decode transform). A codec
can map array to an array, an array to bytes, or bytes to bytes. A codec may
support partial decoding to extract a byte range or array subset without needing
to decode the entire input.
A CodecChain represents a codec sequence consisting of any number of array to
array and bytes to bytes codecs, and one array to bytes codec. A codec chain is
itself an array to bytes codec. A ArrayPartialDecoderCache or
BytesPartialDecoderCache may be inserted into a codec chain to optimise partial
decoding where appropriate.
