Struct Scalar

pub struct Scalar(/* private fields */);

sect283k1 scalar value for use in elliptic curve operations

Implementations

impl Scalar

pub fn new(data: [u8; 36]) -> Result<Self>

Create a new scalar from raw bytes.

The bytes will be reduced modulo the curve order if necessary. The most significant bit is masked to ensure the scalar is < 2^283. Returns an error if the resulting scalar would be zero.

pub fn from_secret_buffer( buffer: SecretBuffer<B283K_SCALAR_SIZE>, ) -> Result<Self>

Create a scalar from a SecretBuffer.

The buffer contents will be reduced modulo the curve order if necessary. Returns an error if the resulting scalar would be zero.

pub fn as_secret_buffer(&self) -> &SecretBuffer<B283K_SCALAR_SIZE>

Get a reference to the underlying SecretBuffer.

pub fn serialize(&self) -> [u8; 36]

Serialize this scalar to bytes.

pub fn is_zero(&self) -> bool

Check if this scalar is zero.

Trait Implementations

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 Drop for Scalar

fn drop(&mut self)

Executes the destructor for this type.

impl Zeroize for Scalar

fn zeroize(&mut self)

Zero out this object from memory using Rust intrinsics which ensure the zeroization operation is not “optimized away” by the compiler.
