Struct Scalar 

pub struct Scalar { /* private fields */ }

The Scalar struct is a wrapper around u64 which has optional fast modular arithmetic through ScalarContext.

fn one() -> T

fn zero() -> T

impl Clone for Scalar

fn clone(&self) -> Scalar

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Scalar

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl From<Scalar> for u64

fn from(item: Scalar) -> u64

Converts to this type from the input type.

impl From<u32> for Scalar

fn from(item: u32) -> Self

Converts to this type from the input type.

impl From<u64> for Scalar

fn from(item: u64) -> Self

Converts to this type from the input type.

impl Mul<u64> for Scalar

type Output = Scalar

The resulting type after applying the * operator.

fn mul(self, v: u64) -> Scalar

Performs the * operation.

impl PartialEq for Scalar

fn eq(&self, other: &Self) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serializable for Scalar

fn to_bytes(&self) -> Vec<u8>

Serialize to a vector of bytes.

fn from_bytes(bytes: &Vec<u8>) -> Self

Deserialize from a vector of bytes.

Performs the - operation.

impl Sub for Scalar

type Output = Scalar

The resulting type after applying the - operator.

fn sub(self, v: Scalar) -> Scalar

Performs the - operation.
