Functions

func CreateSchemaHash

func CreateSchemaHash(schemaID []byte) core.SchemaHash

CreateSchemaHash computes schema hash from schemaID

func DataFillsSlot

func DataFillsSlot(slot, newData []byte) bool

DataFillsSlot checks if newData fills into slot capacity ()

func FieldToByteArray

func FieldToByteArray(field interface{}) ([]byte, error)

FieldToByteArray convert fields to byte representation based on type

func Keccak256

func Keccak256(data ...[]byte) []byte

Keccak256 calculates the Keccak256 hash of the input data.

func SwapEndianness

func SwapEndianness(buf []byte) []byte

SwapEndianness swaps the endianness of the value encoded in buf. If buf is Big-Endian, the result will be Little-Endian and vice-versa.
