For comparision, the group::Group
trait has an associated type Scalar: ff::PrimeField
, which constrains the scalars to be canonical.
from elliptic-curves.
I think this issue is obsoleted by recent changes:
- The type mentioned in the OP is now called
ScalarBytes
and is a type alias toGenericArray<u8, _>
. As bytes, these are expected to be able to contain any value. - Crates with arithmetic each have their own
Scalar
type - The
Scalar
type is now an associated type of theelliptic_curve::Arithmetic
trait
In that regard, the concrete Scalar
types for each crate enforce the invariants described in the OP.
