ff-derive-num

This crate provides a derive macro for num-traits::Num and associated traits for ff::Field implementations derived with the ff-derive crate.

example

use ff::PrimeField;         // ff should be used with the "derive" feature!
use ff_derive_num::Num;

#[derive(PrimeField,Num)]
#[PrimeFieldModulus = "70386805592835581672624750593"]
#[PrimeFieldGenerator = "17"]
#[PrimeFieldReprEndianness = "little"]
pub struct Ft([u64; 2]);
