Functions

func CopyWitness

func CopyWitness(to, from frontend.Circuit)

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 ToBigIntRegular(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

func ShallowClone

func ShallowClone(circuit frontend.Circuit) frontend.Circuit

ShallowClone clones given circuit this is actually a shallow copy --> if the circuits contains maps or slices only the reference is copied.
