Functions

decode_content

Peel the multicodec varint prefix from content bytes. Returns (codec, payload). Legacy messages without a prefix should be treated as codec 0x00 (identity/raw bytes).

default_protocol

encode_content

Prefix payload with a multicodec varint so the codec is self-describing. Common codec values: CODEC_IDENTITY (0x00) raw bytes, CODEC_DAG_CBOR (0x71), CODEC_RAW (0x55). Use CODEC_IDENTITY for plain text — backward-compatible with receivers that treat content as raw bytes.
