Struct Scalar 

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

secp256k1 scalar value for use in elliptic curve operations

Implementations

impl Scalar

pub fn new(data: [u8; 32]) -> Result<Self>

Create a new scalar from raw bytes.

The value must use the canonical big-endian encoding in 1..n. Out-of-range inputs are rejected rather than reduced.

pub fn from_secret_buffer( buffer: SecretBuffer<K256_SCALAR_SIZE>, ) -> Result<Self>

Create a scalar from a SecretBuffer.

The buffer contents must be a canonical non-zero scalar.

pub fn as_secret_buffer(&self) -> &SecretBuffer<K256_SCALAR_SIZE>

Get a reference to the underlying SecretBuffer.

pub fn serialize(&self) -> SecretBuffer<K256_SCALAR_SIZE>

Serialize this scalar to protected exact-size storage.

pub fn deserialize(bytes: &[u8]) -> Result<Self>

Deserialize a canonical non-zero scalar.

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.

fn pin_drop(self: Pin<&mut Self>)

🔬This is a nightly-only experimental API. (pin_ergonomics)

Execute the destructor for this type, but different to Drop::drop, it requires self to be pinned.

impl Zeroize for Scalar

fn zeroize(&mut self)

impl ZeroizeOnDrop for Scalar
