Function registerCBORDecoder

Registers a CBOR decoder for the tagged-contract address (40919) format with the cbor2 library. This enables automatic decoding of CBOR data containing Concordium contract addresses when using the cbor2 library's decode function.

Returns

A cleanup function that, when called, will restore the previous decoder (if any) that was registered for the tagged-address format. This is useful when used in an existing cbor2 use-case.

Example

// Register the decoder
const cleanup = registerCBORDecoder();
// Use the decoder
const tokenHolder = decode(cborBytes); // Returns CborContractAddress if format matches
// Later, unregister the decoder
cleanup();
