macro_rules! MontFp { ($c0:expr) => { ... }; }
Expand description
Construct a Fp<MontBackend<T, N>, N>
element from a literal string. This
should be used primarily for constructing constant field elements; in a
non-const context, Fp::from_str
is
preferable.
§Panics
If the integer represented by the string cannot fit in the number
of limbs of the Fp
, this macro results in a
- compile-time error if used in a const context
- run-time error otherwise.
§Usage
use ark_bls12_381::Fq;
const ONE: Fq = MontFp!("1");
const NEG_ONE: Fq = MontFp!("-1");
fn check_correctness() {
assert_eq!(ONE, Fq::one());
assert_eq!(Fq::from_str("1").unwrap(), ONE);
assert_eq!(NEG_ONE, -Fq::one());
}
