Functions

func ByteLen

func ByteLen(q *big.Int) int

ByteLen returns the number of bytes needed to encode 0 <= n < q

func FieldToCurve

func FieldToCurve(q *big.Int) ecc.ID

func FromInterface

func FromInterface(input interface{}) big.Int

FromInterface converts an interface to a big.Int element

input must be primitive (uintXX, intXX, []byte, string) or implement BigInt(res *big.Int) (which is the case for gnark-crypto field elements)

if the input is a string, it calls (big.Int).SetString(input, 0). In particular: The number prefix determines the actual base: A prefix of ”0b” or ”0B” selects base 2, ”0”, ”0o” or ”0O” selects base 8, and ”0x” or ”0X” selects base 16. Otherwise, the selected base is 10 and no prefix is accepted.

panics if the input is invalid

func Parallelize

func Parallelize(nbIterations int, work func(int, int), maxCpus ...int)

Parallelize process in parallel the work function
