CBORDecoding

Solidity library built for decoding CBOR data.

function decodeMapping(bytes encoding) external view returns (bytes[2][] decodedData)

Parses an encoded CBOR Mapping into a 2d array of data

Name	Type	Description
encoding	bytes	Encoded CBOR bytes data

Name	Type	Description
decodedData	bytes[2][]	Decoded CBOR data (returned in 2d array). Interpretting this bytes data from bytes to it's proper object is up to the implementer.

function decodeArray(bytes encoding) external view returns (bytes[] decodedData)

Parses an encoded CBOR array into a bytes array of its data

Name	Type	Description
encoding	bytes	Encoded CBOR bytes data

Name	Type	Description
decodedData	bytes[]	Decoded CBOR data (returned in array). Interpretting this bytes data from bytes to it's proper object is up to the implementer.

function decodePrimitive(bytes encoding) external view returns (bytes decodedData)

Parses an encoded CBOR dynamic bytes array into it's array of data

Name	Type	Description
encoding	bytes	Encoded CBOR bytes data

Name	Type	Description
decodedData	bytes	Decoded CBOR data (returned in structs). Interpretting this bytes data from bytes to it's proper object is up to the implementer.

function decodeMappingGetValue(bytes encoding, bytes searchKey) external view returns (bytes value)

Performs linear search through mapping for a key. This is much cheaper than decoding an entire mapping and then searching through it for a key.

Name	Type	Description
encoding	bytes	encoded CBOR bytes data
searchKey	bytes	key to search for

Name	Type	Description
value	bytes	decoded CBOR data as bytes

function decodeArrayGetIndex(bytes encoding, bytes searchKey) external view returns (uint64 index)

Performs linear loop through a CBOR array until `searchKey` is found, and returns the corresponding index.

Name	Type	Description
encoding	bytes	encoded CBOR bytes data
searchKey	bytes	key to search for

Name	Type	Description
index	uint64	item position in items where item exists

function decodeArrayGetItem(bytes encoding, uint64 index) external view returns (bytes value)

Returns the value of the Nth item in an array.

Name	Type	Description
encoding	bytes	encoded CBOR bytes data
index	uint64	Nth item index to grab

Name	Type	Description
value	bytes	decoded CBOR data as bytes
