Struct LabeledPolynomial

pub struct LabeledPolynomial<F: Field> {
    pub info: PolynomialInfo,
    pub polynomial: Polynomial<'static, F>,
}

A polynomial along with information about its degree bound (if any), and the maximum number of queries that will be made to it. This latter number determines the amount of protection that will be provided to a commitment for this polynomial.

Fields

info: PolynomialInfo

polynomial: Polynomial<'static, F>
