pub struct Scalar {
pub scalar: secp256k1_scalar,
}Expand description
Scalar is a wrapper around libsecp256k1’s internal secp256k1_scalar struct. It provides a scalar modulo the group order. Storing scalars in this format avoids unnecessary conversions from byte bffers, which provides a significant performance enhancement.
