CBOR is a trusted alternative to JSON, MessagePack, Protocol Buffers, etc. Generic tag decoding. Each data item consists of a header byte containing a 3-bit type and 5-bit short count. To have a specific type generated instead, pass a tags option to the Decoder 's constructor, consisting of an object with tag number keys and function values. Fix those up by calling Decoder. These design goals make it different from earlier binary serializations such as ASN. Where to start Skim through the Crash course section below. Shared value references including cyclic references. Example: encode and decode custom tags This example shows how to encode and decode a custom data type as a CBOR tag: CBOR playgroundCBOR A decoder MUST NOT return a decoded data item when it encounters input that is not a well-formed encoded CBOR data item (this does not detract from the usefulness of diagnostic and recovery tools that might make available some information from a damaged encoded CBOR data item). size、explore techstack and score.
