numcodecs_combinators

Combinator codecs for the numcodecs buffer compression API.

The following combinators, implementing the CodecCombinatorMixin are provided:

• CodecStack: a stack of codecs
• FramedCodecStack: a stack of codecs that is framed with array data type and shape information
• PickBestCodec: pick the best codec to encode the data

Modules:

• abc –

  This module defines the CodecCombinatorMixin mixin, a common interface for all codec combinator classes.

• best –

  This module defines the PickBestCodec class, which picks the codec that encoded the data best.

• framed –

  This module defines the FramedCodecStack class, which exposes a framed stack of codecs as a combined codec.

• stack –

  This module defines the CodecStack class, which exposes a stack of codecs as a combined codec.

Functions:

• map_codec –

  Apply the mapper callable to the codec and return the mapped codec.

map_codec(
    codec: Codec, mapper: Callable[[Codec], Codec]
) -> Codec
