    Module @helia/car

    @helia/car provides import and export methods to read/write Car files to Helia's blockstore.

    See the Car interface for all available operations.

    By default it supports dag-pb, dag-cbor, dag-json and raw CIDs, more esoteric DAG walkers can be passed as an init option.
