Functions

func AddLength

func AddLength(input []uint8, bitLength int) []uint8

AddLength adds a length prefix to the input value.

func CompactToUint8Slice

func CompactToUint8Slice(value *big.Int, bitLength int) []uint8

CompactToUint8Slice encodes a number into a compact representation.

func FromUint8Slice

func FromUint8Slice(input []uint8, bitLength int) (int, *big.Int)

FromUint8Slice retrieves the offset and encoded length from a compact-prefixed value

func StripLength

func StripLength(input []uint8, bitLength int) (int, []uint8)

StripLength removes the length prefix, returning both the total length (including the value + compact encoding) and the decoded value with the correct length.
