Implementations

impl Int64

pub fn constant(value: i64) -> Int64

impl Int64

pub fn alloc_input_fe<F, CS>(
    cs: CS,
    value: <Int64 as Int>::IntegerType
) -> Result<Int64, SynthesisError> where
    CS: ConstraintSystem<F>,
    F: PrimeField, 

Allocates the unsigned integer gadget by first converting the little-endian byte representation of the unsigned integer to F elements, (thus reducing the number of input allocations), and then converts this list of F gadgets into the unsigned integer gadget
