Function registerCBORDecoder

Registers a CBOR decoder for the decimal fraction (tag 4) format with the cbor2 library. This enables automatic decoding of CBOR data containing token amounts 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 decimal fraction format. This is useful when used in an existing cbor2 use-case.

Example

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